In the fast-changing world of electronic music, it feels like a millennium or two has passed since the heyday of deep house. Yet the sound still has its torchbearers, including Tunisian-born DJ/producer Loco Dice, whose devotion to all things dark and chunky has been well documented. On The Lab 01, the first installment in a new mix series from the long-running NRK label, he explores the darker side of house music over the course of two expansive mixes that ultimately clock in at more than two hours. Disc one is an upbeat assemblage of chugging house tunes, while the second CD offers a soulful, spaced-out mix that would serve as the perfect soundtrack to some sultry late-night dancefloor debauchery.
