If there’s one rule people should follow when approaching the Dirty Nil, it’s this: Never tell them how to rock ‘n’ roll. Ontario’s Juno Award-winning trio is a finely tuned rock machine that is at its best when the members are pursuing their penchant for thrashy riffs, bashed out drums, and levels-to-the-max volume. And on their fourth album, Free Rein to Passions, the band followed their instincts down to the note to produce their most authentic work to date.
