Since 1969, when they were still active members of Jefferson Airplane – then one of the hottest rock ‘n’ roll bands in the world – Jorma Kaukonen and Jack Casady have performed together as Hot Tuna, sometimes with a rotating cast of players, sometimes as just a duo.

The Airplane is long gone. Three members of the classic San Francisco lineup are dead – singer Grace Slick, retired more than a decade ago. The band was inducted into the Rock and Roll Hall of Fame in 1996.
