While the first Hot Tuna album had comprised an acoustic trio featuring Jorma Kaukonen, Jack Casady, and Will Scarlet, the second album added violinist Papa John Creach and drummer Sammy Piazza, and most significantly, it added electricity.
Now the sound was closer to Kaukonen's features in Jefferson Airplane.
The highlight was the eight-minute "Keep Your Lamps Trimmed and Burning," although "Candy Man" also became a concert favorite.
