Ruthless
There are at least three with that name, the first was a (fucking sick) Beatdown Hardcore band from Preston City in the north west of england the second being a power metal band from LA, California, and the third one being an alias of DJ Ruthless, a jumpstyle DJ from the Netherlands. 1)"RUTHLESS, A STRAIGHT UP, ANGRY AS FUCK, NO HOLDS BARRED, BEATDOWN BAND FROM THE NORTH WEST OF ENGLAND." 2007 - 2009 RIP
