Did you ever have a crush on one of your teachers? Well get ready to remember how that felt, because if you have as much as a passing interest in either R&B or contemporary electronica you’re likely to fall hard for Jessy Lanza‘s Pull My Hair Back, out September 17 via Hyperdub. A music tutor by day, Hamilton, Ontario native Lanza’s extracurricular activities have produced one of the year’s best debuts: recorded in collaboration with Jeremy Greenspan of Canadian electro-soul duo Junior Boys (whose proto-dubstep classic Last Exit is an obvious antecedent), Pull My Hair Back is a sparse, seductive album that offers vocal skills and sonic thrills in equal measure. If her primary influences – Aaliyah, Mariah, MTVBase circa 1999 -aren’t exactly uncommon these days, Lanza certainly does a better job than most of conveying R&B’s innate hot ‘n’ heavy sexuality: with her breathy moans, excitable wordless ad-libs and saucy lyrics (I’m fairly sure she isn’t asking for assistance in styling her hair in the title track), these tracks are sure to raise eyebrows and temperatures among her students – and their dads – should they get to hear them. A great singer only accounts for half of a great song, though, and Greenspan proves the perfect creative foil, scattering the backdrop with soft focus synth washes, gently percolating electronics, bouncing basslines and shapeshifting beats inspired by UK bass music in all its varied guises. With icy slow-jams mutating into spaced out approximations of footwork (“5785021”), funky house (“Fuck Diamond”), Italo-disco (“Keep Moving“) and more, it’s an album of contrasts, leading you to bed with one hand and dragging you reluctantly onto the dancefloor with the other.
