The afternoon of September 30, 1969, began like any other in Marin County, California, with a green Volkswagen pulling out of a driveway carrying two cats in the back and a young woman at the wheel. Somewhere on the road to the veterinarian, one of the animals leapt into her lap, and the car drifted across the center line into the path of an oncoming school bus. The woman went through the windshield, and that was the end of her. The same week, the harmony she had loved would turn into gold in record shops across America, and the man who loved her was somewhere out on the water or in a studio, not yet knowing that a telephone was about to ring. When it did, David Van Cortland Crosby would walk back out into the rest of his life a different and more dangerous animal. What happened to him over the next two decades, the wreckage and the needles and the loaded pistol and the cell in Huntsville, has the look of a punishment, though no one has ever quite agreed on what the crime was. This is the story of the long strange reckoning of David Crosby, a man born into aristocracy who became one of the most influential voices in rock music, only to be destroyed by grief, addiction, and his own demons. He was born in Los Angeles on August 14, 1941, into a family that wore its history like good tailoring. The Van Cortlands were old Dutch-American aristocracy, the kind of name that came with a manner and a parkway, and his mother, Alice Van Cortland Whitehead, carried that bloodline with a kind of weary gracefulness. His father was Floyd Crosby, an Academy Award-winning cinematographer who had shot the documentary Taboo in the South Seas and would later light High Noon. Floyd was a man who pointed cameras at the world for a living and seemed, to his younger son, constitutionally incapable of pointing any warmth at the boy in front of him. There was an older brother, Ethan, a bassist and a gentle wanderer who taught David his first chords, and who would many years later take his own life. The house was cultured and cold, full of classical records and silence, and David grew up plump, clever, a bit mouthy and unloved in a slightly gothic way that tends to produce either monks or monsters or occasionally rock stars. He was thrown out of schools the way other boys lost retainers, drifting through Santa Barbara and a brief doomed run at junior college. Somewhere in the early 1960s, he discovered the two things that would organize the rest of his existence: folk music and marijuana. He was always honest about the order of operations. I have always said that I picked up the guitar as a shortcut to sex, he wrote later in his memoir, and after my first joint, I was sure that if everyone smoked dope, there would be an end to war. I was right about the sex. I was wrong when it came to drugs. He worked the coffeehouse circuit from Greenwich Village to the Troubadour, a soft-faced kid with a clear high tenor and an instinct for the strange interval, the chord nobody else in the room would have reached for. By 1964, he had fallen in with a guitarist named Jim McGuinn, who had rechristened himself Roger, a wounded angel of a songwriter named Gene Clark, a bassist named Chris Hillman, and a drummer named Michael Clark, who was hired partly because he looked like Brian Jones. They called themselves the Byrds with a Y, and with a 12-string Rickenbacker chiming like a cathedral and a Bob Dylan song they had no business improving, they detonated. Mr. Tambourine Man went to number one in the summer of 1965, and Turn, Turn, Turn followed it to the top by Christmas. They flew to England, met the Beatles, and invented something the press thereafter insisted on calling folk rock. Crosby, all of 23, promptly decided he was a genius and made certain that everyone within earshot knew it. He was not wrong about the gift. His own songs for the Byrds, like the eerie jazz touch drift of Everybody’s Been Burned and the lush doomed single Lady Friend, sailed the band toward stranger and finer water. His high harmony and his churning rhythm guitar was a connective tissue that held the Byrds sound together, and he spent his tenure pushing them toward John Coltrane and Indian raga, while McGuinn mostly wanted another hit single. But he was, by the unanimous testimony of everyone who survived being around him, a colossal pain in the ass. He lectured, he pronounced, and he told his bandmates to their faces that they were not good enough musicians to play with him. At the Monterey International Pop Festival in June 1967, he committed the two sins they would never forgive. First, mid-set, he treated the crowd to an unscheduled lecture on the assassination of John F. Kennedy, announcing that the president had been shot from several directions at once by more than one gun, a public declaration of a conspiracy theory that made McGuinn want to crawl beneath the stage. Then, the following day, he sat in with the rival group Buffalo Springfield, grinning, filling the hole left by Neil Young like a man trying on a new family while his old one stood and watched. The breaking point was a song titled Triad, which Crosby had written in rather frank celebration of a threesome. The Byrds recorded it and then lost their nerve, choosing instead a tidy but comparatively boring Goffin and King number called Going Back. Crosby, disgusted, refused to sing on the replacement. In October 1967, McGuinn and Hillman drove up into the hills to Crosby’s house and fired him from the band he had helped invent. He handed Triad to Jefferson Airplane out of pure spite, and they made it sound more like a witches’ coven at Vespers performing sex magic. But the harsh truth was simple enough. He was out of the band. Years later, in a documentary Echo in the Canyon, Crosby cut through decades of rationalization with a single perfect line. Ladies and gentlemen, he said, looking straight down the barrel of the camera, that is not why they threw me out of The Byrds. They threw me out of The Byrds because I was an asshole. What he did next was fall in love and reinvent popular music more or less simultaneously. Cut loose from The Byrds, he sailed south, and in a club in Coconut Grove, Florida, he heard a Canadian woman with cheekbones like modernist architecture singing songs that seemed to change the literal air in the room. Her name was Joni Mitchell. He became her champion, her lover, and the producer of her first album, Song to a Seagull, in 1968, and he had the rare good sense as a producer to mostly get out of her way. He had also by now acquired the object that would be his refuge for the rest of his life, a graceful old wooden schooner called the Mayan, on which he could sail clean away from every band he was about to destroy. The harmony itself happened by accident in the careless way that history’s best things tend to. In a Laurel Canyon living room in the summer of 1968, either Joni Mitchell’s or Cass Elliot’s, Crosby and Stephen Stills, lately of the imploded Buffalo Springfield, were running through a Stills song called You Don’t Have to Cry. A transplanted Englishman named Graham Nash, miserable inside the Hollies and hunting for an exit, asked them to play it again. Then he sang a third part over the top. The three voices locked into something none of them had ever heard before, a blend so eerie and complete that they simply stopped, stared at one another, and started to laugh. They were a band before they needed a band. Crosby, Stills and Nash, released in May 1969, sounded the way California felt back then, which is to say golden, stoned, and harmonically impossible. Crosby’s contributions were the weird ones and the wounded ones. Guinnevere was a hushed open tuned church of a love song. Long Time Gone was something far darker. He had written it in the stunned hours after Robert Kennedy was gunned down in a Los Angeles hotel kitchen on June 5, 1968, and it carried all the paranoia and grief of a generation watching its leaders mysteriously fall one by one. Wooden Ships, which he wrote with Stills and the Airplane’s Paul Kantner aboard the Mayan, imagined the survivors of a nuclear apocalypse drifting off to sea while the silver people on the shoreline waved goodbye. The record went multi-platinum and won the trio the Grammy for best new artist. For one season, it seemed to hand the exhausted idealism of the decade somewhere quiet to live. They needed muscle to take it on the road, so they added Neil Young, the very man Crosby had effectively cuckolded on stage at Monterey, and became Crosby, Stills, Nash and Young. Their second concert ever took place in the small hours of August 18, 1969, in a field in upstate New York at a festival called Woodstock. Half a million people lay out in the dark, in the wings to Jimi Hendrix and a good portion of the rest of rock and roll, waiting to see whether these four difficult men could actually do the thing. This is only the second time we have ever played in front of people, Stills told the crowd after the opening song, his voice audibly shaking. We are scared shitless. Then they opened their mouths and the fear turned into something close to a sacrament. For one impossible season, they were the biggest band in America. Deja Vu, released in March 1970, went straight to number one and stayed there, four bruised egos and four enormous talents briefly pulling in the same direction. Crosby’s own Almost Cut My Hair became the snarling paranoid heart of it, a man refusing to trim his freak flag while the whole establishment leaned on him to conform….
