Typical of a lot of 2 piece bands, Monastr sounds like a 10 piece such is the noise that eminates from the debut full length On Your Knees. The album follows the usual post - metal formula, moments of quiet, brackish reflection before the sludge kicks in. The sludge riffs in On Your knees are too weighty to rise above ground level. A lot of post- metal bands are tagged with sludge, some disappoint but Monastr deliver granite riffs of ground shaking proportions.
