Carol Kaye - the most recorded bass guitarist in music history, with a career spanning over 65 years and having performed on over 10,000 recordings. A trained jazz guitarist who transitioned to bass almost by accident (the bassist who was booked for a session didn't turn up), she became first-call bass player for LA/Hollywood recording sessions throughout the 60s, 70s & into the 1980, in the face of the rampant sexism ingrained in the business.
Also a prolific tutor & educator since 1957, she is still alive & kicking at the age of 90, and well worth a follow if you're on FB & have any interest in music.
