Orthrelm is a instrumental guitar/drums duo founded in the summer of the year 2000 by guitarist Mick Barr and drummer Josh Blair. They were initially
known for playing extremely complicated compositions with little or no repetition whatsoever. However in 2005 they received alot of attention, praise and
criticism for their extended minimalist piece "OV" (Ipecac, 2005) which instead utilized repetition to the extreme.
