Signe Anderson, one of the original vocalists for Jefferson Airplane, has died at the age of 74.

The singer, who appeared only on the band’s first album, Jefferson Airplane Takes Off, died last Thursday – the same day as guitarist Paul Kantner.

“One sweet lady has passed on,” wrote the rock group’s co-founder Marty Balin on his Facebook page.

“I imagine that she and Paul woke up in heaven and said, ‘Hey, what are you doing here? Let’s start a band!'”

No cause of death was given for the singer, but former band mate Jack Casady said she had been receiving hospice care.
