by Tony WildsAfter several, probably ill-advised collaborative (or sideman) efforts, Esquivel returns to his full glory on Infinity in Sound. This is the second album -- after Exploring New Sounds in Stereo -- of the"typical" Esquivel, who pushed the envelope of stereophonic"gee-whiz-ardry." Several tracks are recycled in LP and CD compilations. While"Johnson Rag,""Harlem Nocturne,""Take the 'A' Train," and"Frenesi" are all good examples of Esquivel in his prime, the chief attraction of the album is its consistency and overall integrity. It is a relief that Esquivel is not trying anything stranger than he already is. However, it is not quite his best or most interesting work.
