Born in hotel rooms after laying down the lightning and the thunder for the Jefferson Airplane; Jorma Kaukonen and Jack Cassidy return to their roots with Hot Tuna. Recorded at a coffee house, this album has the feel of the classic blues of the early 60s, ESPECIALLY Brownie McGhee and Sonny Terry's LIVE AT THE 2ND FRET.Kauakonen and Cassidy (with harmonica player WIll Scarlett) made a siginficant step tword their future by forming this side group. Kaukonen shows off a love for the blues of the Rev Gary Davis and Jelly Roll Morton and Cassidy contributes his always awesome bass work, with Scarlett sliding in and out with them.For lovers of the blues who aren't absolute PURISTS, this is a great set. Anyone interested in the influences of the California rock bands of the late 60s/early 70s should pick this up.
