Melody and relaxation are the last things that come to mind when listening to Joel Mull. The Swedish techno DJ & producer is known for his punishing DJ sets and Gazometertraxx: Water is no exception. Recorded live at the Gazometer rave in Vienna in March 2003, the 18-track compilation features thunderously brutal techno by Mull, Marco Bailey, Hardcell, DJ Rush and James Ruskin, among others. Pummeling techno can be an acquired taste, and while this is a seamless mix, listening to the rapid-fire rhythms at home just can’t compete with a booming club sound system. For heads only.
