Crowbar
Crowbar are considered to be the real inventors of the 'doom-core' genre, combining the heaviness of doom metal and the breakdowns of hardcore. Their first release back in 1992, Obedience Thru Suffering, set the tone for a whole new range of bands to arise from the depths of metal and hardcore. The album was an inspiration for many people to pick up an instrument and start making heavy music without following any rules. The record has been out of print since 1994, but now, the band re-released their debut masterpiece.
