Aside from the experimental side project Lumpy Gravy, Hot Rats was the first album Frank Zappa recorded as a solo artist sans the Mothers, though he continued to employ previous musical collaborators, most notably multi-instrumentalist Ian Underwood. Other than another side project -- the doo wop tribute Cruising With Ruben and the Jets -- Hot Rats was also the first time Zappa focused his efforts in one general area, namely jazz-rock. The result is a classic of the genre. Hot Rats' genius lies in the way it fuses the compositional sophistication of jazz with rock's down-and-dirty attitude -- there's a real looseness and grit to the three lengthy jams, and a surprising, wry elegance to the three shorter, tightly arranged numbers (particularly the sumptuous &Peaches en Regalia&). Perhaps the biggest revelation isn't the straightforward presentation, or the intricately shifting instrumental voices in Zappa's arrangements -- it's his own virtuosity on the electric guitar, recorded during extended improvisational workouts for the first time here. His wonderfully scuzzy, distorted tone is an especially good fit on &Willie the Pimp,& with its greasy blues riffs and guest vocalist Captain Beefheart's Howlin' Wolf theatrics. Elsewhere, his skill as a melodist was in full flower, whether dominating an entire piece or providing a memorable theme as a jumping-off point. In addition to Underwood, the backing band featured contributions from Jean-Luc Ponty, Lowell George, and Don &Sugarcane& Harris, among others; still, Zappa is unquestionably the star of the show. Hot Rats still sizzles; few albums originating on the rock side of jazz-rock fusion flowed so freely between both sides of the equation, or achieved such unwavering excitement and energy.
