Her weird name was the least of Moon Unit Zappa’s problems

On Frank Zappa’s first date with Gail Sloatman, he blew his nose on her skirt. As acts of territory-marking go, it’s hard to imagine something more equivocal. But Gail, a 20-year-old secretary at Los Angeles’s Whisky a Go Go club, must have read it as love. She built her life around the musician, composer and ‘rock’s most committed iconoclast’, as his New York Times obituary described him, for 27 years, until his death from prostate cancer in 1993, aged 52.

A year after that first, snot-filled seduction, the Zappas were married, a week before Gail gave birth to Moon Unit, the first of four children. Moon’s name is not a compound noun: Unit is her middle name, given to reflect how her arrival turned two people into a single family – Frank’s idea.

Moon’s memoir is partly a meditation on a lost milieu, a portrait of the Laurel Canyon countercultural landscape of the 1970s and 1980s, made lucid through a child’s eyes.
