Butter Sessions Vinilo y CD

Review: Since debuting a decade ago, Sleep D has refused to settle on one specific style or sub-genre, though in recent years the duo seems to have settled on a sound that prioritises hallucinatory, TB-303-driven sounds, weighty techno grooves and nods towards mid-90s ambient techno. These elements are much in evidence on the Australian outfit's latest EP, though there are also audible nods to neo-trance and the formative years of the psy-trance movement. They first join forces with Ivy Barkakati and Furious Frank on the constantly rising, mind-altering neo-trance throb of 'Border Control (Ahora Si)', before reaching for seriously trippy electronic motifs, creepy chords, metallic-sounding electronic bass and sturdy house beats on 'Post Pump'. Closing cut 'Bass'd in Berlin', meanwhile, immerses us in ambient electronics and mutilated choral samples before introducing a seriously pulsating, trance-style groove.
