Death Grips isn't the last group you'd expect to possess an air of fatalism, but it wouldn't be the first, either. The biggest question with the Sacramento, California, trio — outbursting vocalist MC Ride, pugilistic drummer Zach Hill and producer/fixer Andy Morin — wasn't whether they had lasting impact, but whether they would last long enough to realize it. Just as furiously as their star ascended (two web releases bookending two landscape-razing studio LPs in three years), it imploded. A conflict with label Epic prompted an intentional leak of 2012's No Love Deep Web, with a cover image of the title scrawled across an erect penis; so long, record contract. Another year culminated in a high-profile Chicago nightclub no-show, a Lollapalooza cancelation and a mob of outraged fans releasing their frustration on the band's gear. In 2014, Death Grips announced plans for a mammoth double album (The Powers That B), issued the first half in June under the name Niggas on the Moon, and abruptly broke up a month later — the news coming via a note on a napkin posted to Facebook. As if the music wasn't divisive proof enough (utterly unclassifiable, but with a gun to your head, 45 rpm Bad Brains splattered by .45 caliber electro), these were the actions of a band on the brink. Just as flippantly, they're back: completing the Moon cycle with an even darker back half (Jenny Death), promoting a new outfit no one's ever heard of (The I.L.Y.'s) and expanding this comeback tour into October. Best catch it now before the inevitable eclipse. Tickets $25.
