It sounds simplistic, but few electronic artists ever go for full-on optimism. The Bell brothers aren’t interested in the negative: Their full-length debut, Love Your Abuser, keenly plumbs the depths of good cheer with lush melodies and a rich sampling of electronic textures. What keeps Abuser from sounding precious is a certain contemplative quality and a clear attention to song structure. The Bells love their melodic moments: Lone piano notes ripple like sonic pools on “Idle Wires,” while the cinematic “Fall Bicycle” could provide a percussive soundtrack to your coolest drug-induced dreams.
