The cause of death has not been disclosed.
The Jefferson Airplane band was founded in 1965 in San Francisco by Marty Balin and guitarist Paul Kantner, who died in 2016 at the age of 74.
The band continued under the name Jefferson Starship. On Facebook, the group announced the death of Balin on Saturday. “With a heavy heart we hear today that Marty Balin died, he was a great talent and a source of inspiration for many, and our condolences to his family and friends.”
Balin underwent heart surgery in 2016. In August he filed a lawsuit against the New York City hospital because he believed that he had suffered damage to his tongue and vocal cords during the operation.
Well-known songs from the band are “Somebody To Love”, “We Built This City” and “Nothing’s Gonna Stop Me Now”.
Jefferson Airplane played at Woodstock in 1969 and got a spot in the Rock and Roll Hall of Fame in 1996.
