You didn't hear that Workshop was back?! We've been listening to these guys since Bob the Builder was a member. Workshop are one of the most overlooked heavy metal innovators of the past 40 years.

In fact, the band pioneered the popular and crushingly heavy sub-genre 'Mortise Metal,' which is derived from the terminology for a slot cut into a board, plank, or timber (usually edgewise), to receive the tenon of another board, plank or timber to form a joint. You may laugh at these fine men (especially the one on the very right), but if you don't know Workshop, you don't know nothin'.
