Where the forefathers of heavy psych and prog-metal left off in the mid '70s, Mondo Drag has picked up today. The Oakland outfit sets Sabbath-y guitars against melodies distorted by echo and phaser effects. These surreal soundscapes are infused with keyboard and synth passages reminiscent of the early years of Yes. A song like "New Rituals" showcases the group's dynamic by starting with an ominous drone, then building to upbeat tempos and chaotic interludes that highlight the band members' musicianship. Expect Mondo Drag's Bottom of the Hill show this week to be a mind-trip.
