Many of the bands who occupy this list were formed before the dawning of the new millennium, but there are a few that began in the 2000s and are already considered as heroes of their genre.

Baroness released 'Blue Record' in 2009 to mass critical acclaim. Considered as the sister to Baroness' debut, 'Red Album,' the Georgian sludge merchants composed a true opus in 'A Horse Called Golgotha'. Baroness has demonstrated with this track, and their entire discography, that you can make beautiful music while remaining brawny, masculine and heavily-bearded in your approach.
