With music that's equal parts insanity and ingenuity, the appropriately named Dysrhythmia is an intellectual firestorm of sound. They're smart enough to create complex rhythms and harmonies but wild enough to keep it heavy and gritty. It's easy to get lost in the academic nature of their songwriting but the awesome drive of the music is what brings you back for more. The members' wildly diverse tastes (two side projects include ambient synth electronica and a solo baritone ukulele album) come together amazingly well in the self-described blend of prog rock, jazz and heavy metal. Heavier than ever, their newest record Test of Submission shows an intensity of their signature complex destruction. The band's personal blog hints that this may be their last time touring for a while. Presumably, they're taking time off to write and record new songs or write a compelling academic thesis on Joyce's Ulysses — judging by their varied sources of inspiration, either seems possible.
