Dysrhythmia

Tech-metal nerds best saddle up in a fresh pair of Depends to prepare for the hyper-math jujitsu from this Relapse Records instrumental trio. Quoting equally from the proggy tomes of Mahivishnu Orchestra and King Crimson, as well as the underground tech-schools of Atheist and Cynic and the post-rock metal academies of Don Caballero and Mastodon, these shredders pack every kind of guitar squiggle, squeal, twist, and burn with high grade titanium—the heavy is not lost in all the complexity. With Stats and the Smother Party.
