Born Grace Barnett Wing on October 30, 1939, in Highland Park, Illinois, Grace Slick became the commanding voice of San Francisco's psychedelic scene after joining Jefferson Airplane in late 1966, replacing original singer Signe Toly Anderson. She brought two songs from her previous band, The Great Society, into the fold, and both became defining hits on 1967's Surrealistic Pillow: the tense, Alice in Wonderland inspired "White Rabbit" and the soaring "Somebody to Love," both reaching the US top 10 and helping turn the Summer of Love into a soundtrack. When Jack Casady and Jorma Kaukonen split off to focus on Hot Tuna, Slick and Paul Kantner formed Jefferson Starship, and she later fronted the 1980s incarnation Starship through chart toppers "We Built This City" and "Nothing's Gonna Stop Us Now" before retiring from music in 1989.

Born on October 30, 1947, in Oakland, California, Timothy B. Schmit built a career as rock's go to harmony voice, first with Poco, which he joined in 1969 after losing an earlier audition to Randy Meisner, and where he wrote and sang Poco's breakout hit "Keep on Tryin'." History repeated itself in 1977 when Schmit again replaced Meisner, this time stepping into the Eagles following their Hotel California tour. He sang lead on "I Can't Tell You Why," a top 10 hit off The Long Run, and later carried the ballad "Love Will Keep Us Alive" on the band's 1994 reunion album Hell Freezes Over. His falsetto also turned up on other people's records, most famously riding the high register ending of Toto's "Africa" and backing vocals on Steely Dan's Aja.

Born on October 30, 1965, Gavin Rossdale formed Bush in London in 1992, originally called Future Primitive, after striking up a songwriting partnership with guitarist Nigel Pulsford. Despite grunge having broken out of Seattle rather than Britain, Bush's 1994 debut Sixteen Stone became a massive American success, going multi platinum on the strength of tracks like "Glycerine" and "Comedown," even as the band struggled to find the same traction back home in the UK. Rossdale's smoky baritone and brooding lyrics carried the band through Razorblade Suitcase and beyond, making Bush one of the best selling rock acts of the decade before they split in 2002. He reunited the band in 2010 and has kept releasing new Bush albums ever since, most recently I Beat Loneliness.
