BioBlue Cathedral is the third album from Comets on Fire and their first for Sub Pop. It is also the Bay area band's most varied and richly textured album yet. With their first two albums, (2001's self-titled debut/self-released and 2002's Field Recordings from the Sun on Ba Da Bing!) they established themselves as flag-bearers of modern psychedelia. However, where their previous efforts are full-tilt psychedelic affairs, Blue Cathedral is harder to pin down (which elusiveness we heartily support). Their trademark sound is here enriched by more structured, keyboard-driven jams, churning Blue Oyster Cult-ish chooglers and slow burners reminiscent of Harvest-era Pink Floyd.
