Double LP version. With its cathedral-like, richly resonant acoustics, the new Hypnotic Brass Ensemble album Book Of Sound is a brilliant expression of this interplanetary principle. The album is by turns urgent and contemplative, funky and reflective, varied in its textures; but entirely of one piece. Underpinned by concepts of earth’s place in the cosmos, held in place by meditation, swirling with notions of history, science, theology, ancestry, there is a rich conceptual brew here. The album rings with what back in the 1950s the jazz critic Whitney Balliet called “the sound of surprise”. Book Of Sound makes you believe again in the validity of “spiritual jazz”.
