Geoff White had been building a reputation for heady minimal techno until his debut full-length as Aeroc, Viscous Solid, revealed a particular genius for placing acoustic sounds in a decidedly digital context. While seven years removed from that release, Aeroc's R+B=? displays the same out-of-time qualities as its predecessor. Melody is paramount on R+B=?'s eleven gentle instrumental pieces. Most feel as though they were written on acoustic guitarbefore White's tinkering production frayed the edges, amplified subtle resonances and teased counter rhythms out of the space between his stringsbut its the simple, undeniable tunefulness and musicianship that makes R+B=? so memorable. Although White limits his source material, R+B=? cant truly be described as minimal, as theres a pervasive rich, earthy melodicism coursing through the remarkably unified album. Along the way, strains of future-funk (If I Had the Time), pseudo hip-hop beats (Playing String), languorous balladry (It Does Easy), spiraling glitch workouts (Avalon Blonde) and echo-drenched snares (Some Kisses) work their way into the mix of guitar and keys.
