Pinnacle were a heavy rock band from Liverpool. Pinnacle was their only album. Music similar to Black Sabbath, according to some reviewers. Some describe them as early progressive or space rock. The album is described as follows: Musically, this is a sonic assault with pounding drums and bass and frenzied keyboards. Powerful stuff indeed. A sort of prototype heavy metal album that was originally only available as a demo. Clearly of interest to heavy rock/metal fans. "These guys where certainly onto a fairly early metal sound somewhat similar to early Judas Priest and Deep Purple, although I'm pretty sure this bands real biggest influence was the mighty Hawkwind."
