Marcus Kaye and Lee Ching became friends in the early '90s, when they were at the forefront of a progressive drum and bass movement under their respective Marcus Intalex and DJ Lee monikers. Despite their history, Sideways is their first collaborative project. Retraced is a euphoric journey with rich strings over a hefty bassline, while Minor Difference goes straight for the four-to-the-floor approach, ripe for a crowded, dark dance floor. PJ's Groove is the throwback. With crisp open hi-hats, warm organ stabs, and big washed-out pads, it feels like a trip down memory lane, yet with an updated, modern twist.
