Ms. Davis's unique story is unlike any other in popular music. Betty wrote the song "Uptown" for the Chambers Brothers before marrying Miles Davis in the late '60s, influencing him with psychedelic rock, and introducing him to Jimi Hendrix -- personally inspiring the classic jazz-rock fusion album 'Bitches Brew.' Betty not only wrote every song she ever recorded and produced every album after her first, but the young woman penned the tunes that got The Commodores signed to Motown. The Detroit label soon came calling, pitching a Motown songwriting deal, which Betty turned down. Motown wanted to own everything. Heading to the UK, Marc Bolan of T. Rex urged the creative dynamo to start writing for herself. In 1973, Davis would finally kick off her cosmic career with an amazingly progressive hard funk and sweet soul self-titled debut.
