A type of punk music that basically plays as fast as humanly possible with lyrics that don't even attempt to be audible or important.

power violence 

A loosely defined sub-style of hardcore which almost completely eschews traditional song structure in favor of an all-out blitz-speed musical attack. More well-known power violence bands include Infest, Spazz, and Scholastic Deth.

That band is more grindcore than power violence, but they use elements of both.
