Hot Tuna, now a quartet with the official addition of keyboardist Nick Buck, released this two-LP live album, its first concert material in seven years, and having thus summed things up, broke up as the album hit record stores. Double Dose gave a good sense of mature Hot Tuna as a vehicle for the musical interests of Jorma Kaukonen, who used the entire first side as an acoustic solo set, then included the excellent "Genesis" from his solo album Quah on side B. Elsewhere, the electrified group alternated between Kaukonen's best Hot Tuna compositions and blues and rock standards. It was produced by Felix Pappalardi (Cream, Mountain), who gave Hot Tuna its best recorded sound; even though it's a "live" record, there seems to have been a lot of studio overdubbing.
