Hot Tuna
Hawaiian Hut / 941-5205

For more than 50 years, Jorma Kaukonen and Jack Casady (left and center) have played music together. As members of the Jefferson Airplane, the two helped shape the sound of the '60s, but still kept up with developing new material for what was a side project at the time.

Now, decades later, the duo is known as Hot Tuna and they continue to record and tour. Tickets for Friday's show are $50; doors open at 8:30 p.m.
