In just six tracks, Bay Area producer Bassnectar fuses a host of influences into a devastating package as heady as it is heavy. The flickering synths of “Arps of Revolución” are akin to ’90s IDM, while the thundering “Underground” hammers vintage rave stabs over trap drums and a punishing dubstep drop. The secret weapon might be “Was Will Be,” which pairs jump-up drum programming and bright, soaring synths with Mimi Page’s sweetly Auto-Tuned vocals. Buoyant and brutal, it’s everything you want in a festival anthem.
