Chunga s Revenge largely eschews both high concept and satire in order to focus on the considerable jamming expertise of Zappa and his cohorts. The album was divided into two discrete halves. The first side consists of extended, largely instrumental pieces where Zappa and his musicians stretch out and show off their improv chops over relatively simple, often blues-based structures. The keyboard-based instrumental interlude Twenty Small Cigars provides an interesting semi-classical change of pace. Side two contains shorter, vocal-oriented numbers, with harmonies that draw on the doo-wop influence of Zappa youth (a recurrent element in his work). Slightly schizophrenic though it may be, Chunga s Revenge is something of a showcase for the members of Zappa group, displaying their vocal and instrumental interaction to fine effect.
