Just one day after co-founder Paul Kantner died comes news that Jefferson Airplane’s original female vocalist has passed away.  The band’s Marty Balin posted the sad news on his Facebook page that Signe [SIG-nee] Anderson has died.

“One sweet Lady has passed on,” Balin writes.  “I imagine that she and Paul woke up in heaven and said ‘Hey what are you doing here? Let’s start a band’ and no sooner then said Spencer was there joining in! Heartfelt thoughts to all their family and loved ones.”

“Spencer” is former Jefferson Airplane drummer Spencer Dryden.  He died in 2005.

Anderson sang on Jefferson Airplane’s first album, 1966’s Jefferson Airplane Takes Off, but left the band not long after the birth of her baby making way for Grace Slick to join.

There’s no word yet on  the cause of death but she had recently moved into a hospice.  Signe died on Friday, the same day as Kantner.  She was also the same age as Kantner — 74 years old.
