This band's profile is 'invisible', meaning that it's much less prominent on the site - either because it's incomplete, or maybe doesn't entirely fit MS format.




1998 - Kevin Hufnagel calls Clayton Ingerson...says he has some riffs he wants to show him. A few riffs turn into 5 or 6 songs. We begin auditioning drummers to no success.
1999 - Dysrhythmia is born. Drummer Jeff Eber is found through a psychic dream. We play our first show ever, in Philadelphia, PA, at the legendary Stalag 13 with Discordance Axis, and Ruins. Purchase a used van for $1,000 and begin to think about touring.

2000 - Our first record 'Contradiction' is self-released and limited to 500 copies. Recorded on 16 track analog reel-to-reel in a basement in South Jersey over two weekends. Embark on our first DIY tour. Continue playing to the same 5 people in Philadelphia.

New material begins to develop yet bassist Clayton Ingerson eventually leaves the band. Colin Marston enters. Dysrhythmia continue on, writing and now rehearsing in Brooklyn at Colin's studio while Kevin makes trips up from Philadelphia and Jeff down from Boston. All for the love of the instrumental rock.
