Wilson Phillips first appeared in 1990 flaunting a harmony-rich sound that helped send three singles from their first album -- "Hold On," "Release Me," and "You're in Love" -- to the top of the Billboard charts. Carnie Wilson, Wendy Wilson, and Chynna Phillips comprised the vocal trio, whose sudden success was matched by an equally impressive pedigree. The two Wilson sisters had grown up in California with their father, Beach Boy bandleader Brian Wilson, and often made appearances on his albums throughout their childhood. Chynna's parents, meanwhile, were John and Michelle Phillips (of seminal folk-rock band the Mamas & the Papas). Despite growing up alongside such icons, the girls first pursued separate careers in acting and modeling, only turning to music when Chynna (having been influenced by Band Aid and Farm Aid) suggested they make a charity record with other children of famous musicians. The project fell through, but it also brought the three girls together again, forming Wilson Phillips in the process.
