Hot Tuna (also the name of an Ozzie surf brand randomly) is made up of co-founders and continuing core members Jorma Kaukonen and Jack Casady, a duo with a unique combination of blues, jazz, bluegrass & folk influences. They've been making music together for fifty years, playing together as teenagers and later in the iconic '60s band The Jefferson Airplane, where Kaukonen played lead guitar and Casady was on bass.
