Savy Records celebrates its fifth year with Lumo, a new vinyl-only series built around the darker corners of the dance floor. The first edition gathers four artists whose productions move naturally through the night -- from tension and space to drive and release. The record opens with Andy Martin, a Mexican-Jamaican artist whose dub-infused ''Wicked Tune You Know'' nods to UK bass influences, with a percussive undertow and an addictively off-kilter synth line. Finnish favourite Sansibar makes his return to the label with ''Innerwelt,'' a twisted electro cut laced with acid paranoia and washed-out vocals, slightly unsteady but always in motion. On the flip, IDA -- fellow Finnish export and SAVY label founder -- keeps things tight with ''Electrostatic Rest,'' a straight-up electro roller built on clean drums and a classic electro bass, one to lock in the dancefloor groove with. Lewski closes with ''Glakk,'' a machinated, bass-heavy analogue banger, driving up the tempo as it heads up the peak time. Lumo presents a darker, deeper side of Savy: one that nods to the underground, and cut for purpose as a vinyl-only release.
