Metaladdict4life has 1 Tetrarch concert.

If there is one thing TETRARCH can unequivocally claim, it’s that they are quite possibly the most tenacious heavy band on the planet. Over the course of several harrowing months in which many bands were forced to hang up their hats or slam to a screeching halt, TETRARCH accepted the challenge and manifested their most successful year to date. Now, with the impending release of their sophomore album Unstable looming, the Los Angeles four piece has the world standing at attention.
