Festival habitués, having visited thrice with the electro-pop supergroup Moderat they led with countryman Sascha Ring, Berlin artists Gernot Bronsert and Sebastian Szary are back with their basses, reawakening their most famous project after an eight-year slumber. With twenty years’ activity generating an intimidating volume of singles, remixes, and five-star collaborations (Thom Yorke, etc.), this German duo is now presenting Who Else (2019). This fourth album features mixed electro with beats that savage all that moves and breathes, and in which the least instrumental borrows equally from corroded industrial and lacy ambient. Major on disc, imperial on stage, these Berghain regulars, who also head up the label Monkey Town, promise to bring fire and fun to Montreux.
