Sonny Simmons comments: "Ideas make a civilization of music". This second volume of solo performances brings forth the complex and brilliant horn algebra which made Simmons famous in the free jazz era. Fourth Dimension is indeed music conceived as out of our physical universe. Sonny Simmons unfolds a new world of music to explore, in a bright manner already exemplified by two points of reference in solo improvisation, Anthony Braxton and Roscoe Mitchell. Here Sonny's peculiar, meditative cor anglais, his explosive and mathematical alto sax create a unique language, which can only be described as jazz's babylonian ancestor, or one of the music's future development, - not today's jazz, nor its immediate past, nor its immediate future. Listen, and learn.
