Feeling that he needed a singer to compete commercially, Mandel decided to abandon his instrumental format, taking on multi-instrumentalist Russell Dashiel as lead vocalist for a good share of the tracks. Dashiel was a singer who typified some of the lesser White blues-rock stylings of the period, and the material (with a higher percentage of blues and soul covers). Harvey's playing remained accomplished and imaginative (as is evident on the original instrumental "Ridin' High" and the cover of Horace Silver's "Senor Blues").
