2012 release from the Extreme Instrumental Jazz/Fusion Metal band. Brooklyn, NY's Dysrhythmia formed over a decade ago and are among the pioneers of this new movement. Nobody else in the early '00s was doing what they were doing, and it's no surprise that the forward-thinking Relapse Records took notice. Over the course of three full-length albums for the label and countless jaw-dropping live shows, Dysrhythmia built a fanbase that ranged from extreme metal-heads to extreme music nerds.  Test Of Submission is the darkest and most intense of their already storied career. Dysrhythmia prove themselves light years beyond the current crop of instrumental virtuosos, and it's important to note that they compose actual songs with proper structures instead of merely showcasing the fact that they can play the living hell out of their instruments. Witness them wipe the floor with the competition on their most triumphant work yet.
