Daniel Lopatin's first album for Warp traded the analog drift of his earlier work for something brighter and more disorienting: sampled choral voices, MIDI woodwinds and organ patches cut together with the logic of a half-remembered menu screen. R Plus Seven is where Oneohtrix Point Never stopped sounding like ambient music and started sounding like a building you walk through. Lopatin drew on choral work written for Saatchi and Doug Aitken's Hirshhorn installation, then assembled the record as a branching path through his own past. Warp presses it across two 140g LPs in a gatefold sleeve.
