Rise Records is a tiny operation - just six employees at a modest office in Beaverton, Ore. But in the metal music world, the independent label is making a surprisingly loud noise. Three of its albums have cracked the top 10 of the Billboard 200 so far this year, including "Unconditional" by Dallas metalcore outfit Memphis May Fire, released in March (No. 4). Rise is responsible for nearly 5 percent of all hard-rock records sold in 2014 - more than twice the market share of older and more established competitors like Hopeless Records and Epitaph.
