Rytmihäiriö is a Finnish punk/metal band formed in 1988 in Helsinki. They disbanded in 1992 after a few releases on Spinefarm Records, with some of the members going on to form crust punk band Wind of Pain, before regrouping once more in 1998. The band's first incarnation featured a fast and raw style of music, bordering on grind and thrashcore at times, while their more recent releases are more conventional crossover thrash.
