Omnium Gatherum's sprawling 16 tracks of gonzoid prog jams, dizzying pop nuggets, rubber-legged hip-hop odysseys and passages of pure thrash-metal abandon offer plenty for Gizzard fans and neophytes alike to chew on. Typically, Gizzard albums pursue a single theme or style - but part of the thrill of O.G. for the group was the opportunity to present new ideas without committing the entire album to just one. It's both the perfect entry point for newcomers, and a solid treat for the faithful.180g Cosmic Black double LP.
