Signe Toly Anderson, a vocalist and original member of the Jefferson Airplane who left the band after its first record and was replaced by Grace Slick, has died.
Anderson died Thursday at her home in Beaverton, Oregon, according to her daughter, Onateska Ladybug Sherwood.
Anderson was 74 and had been suffering from chronic obstructive pulmonary disease. She died on the same day that another founder Airplane member, Paul Kantner, died.
A native of Seattle and longtime Oregon resident, she joined the San Francisco-based Airplane in the mid-1960s and sang on their first album, "The Jefferson Airplane Takes Off."
By the summer of 1966, however, she was pregnant with her first child and decided to leave. That fall, Slick joined the group, which shifted from folk-rock to a harder, psychedelic sound.
