50. Death Grips, 'Bottomless Pit'
It's remarkable to think that noise-rappers Death Grips once seemed as unstable as radioactivity: battling record labels, canceling shows and presumptively announcing their breakup via napkin in 2014. Two years later, the Sacramento trio has evolved into a dependably provocative unit that operates at the nexus of punk rock, live electronics and barking energy raps. Fifth album Bottomless Pit offers further refinement: "Giving Bad People Good Ideas" rattles like an old industrial banger, "Hot Head" applies breakcore dynamics like smeared lipstick and "Warping" stutters on a toy piano melody. Then there's MC Stefan Burnett, an animated and muscular presence who splits the difference between DMX and Henry Rollins, and whose vocal performance goes beyond mere war chants. When he quietly shrugs "Eh" over Andy Morin and Zach Hill's whirligig rhythm, he sounds just as devastating as when he's bellowing "My death is money" on "Ring a Bell." M.R.
