Pioneers of the English space-rock underground, Ozric Tentacles have been rearranging brain cells since 1982, when their expansive, instrumental workouts drew comparisons to such better-known space cadets as Pink Floyd and Hawkwind. Champions of the pretentious album title (Pungent Effulgent, anyone?), the merry minstrels have nonetheless racked up an impressive back catalog since their experimental heyday of cassette-only releases. OT showcases founder Ed Wynne's bold, heavily processed virtuoso guitar -- arguably the missing link between Joe Satriani and Buckethead -- which is augmented by contributions from quasi-classical flutist John Egan, bassist Pazza, and drummer Schoo, as well as the celestial organ licks of new keyboard wizard Hal Waters (son of Floyd visionary Roger Waters, he's Ozric veteran Seaweed's heir apparent). Hitting the road on a rare Stateside tour, the mighty Oz blends dub, psychedelia, ambient trance, and dance into a seamless, free-form aural experience suitable for framing. The Tentacled Ones boast one fierce live unit, by tuttle.
