Long before the rise in interest in African music, British electronica producer Bob Holyroyd was making tracks rich in traditional instrumentation. "African Drug" is, undoubtedly, the most famous of these. Originally released as a single in 1994, the intensely melodious, Steve Reich-esque work has been remixed numerous times over the years. This latest edition arrives on Joaquin "Joe" Clausell's Sacred Rhythm label, with profits going to charities that work to save Africa's endangered Rhino. The A-side contains a freshly mixed and re-mastered version of Holroyd's brilliant original - which brilliantly increases in intensity with the addition of tribal drums two thirds of the way through - with a more percussive, pleasingly hallucinogenic Clausell remix on the flip. In a word: essential.
