That article only covers a small number of the significant sessions she made. Clydie King, usually together Venetta Fields and Sherlie Matthews, were the go-to backing for many Los Angeles recording sessions for the majority of the 1970s. They were not always credited, or simply credited as The Blackberries.
Other acts she definitely worked with include Captain Beefheart (on 'Clear Spot'), Tim Buckley (on 'Greetings From LA'), Gene Clark (on 'No Other'), and possibly Stevie Wonder (on 'Music Of Of Mind' - uncredited). There's also some other less worthy acts she backed up - she's on Leo Sayer's 'Endless Flight' (available from a charity shop near you) and possibly also a James Last album (he recorded 'Best Kept Secret' in LA with the usual LA session crew, and Venetta Fields is pictured on the back cover).
