Grandbrothers will tour Europe and the UK in November, showcasing tracks from their second album, Open, which will be released by City Slang Records on October 20, as well as 2015's acclaimed debut, Dilation. The duo, Erol Sarp and Lukas Vogel, first met seven years ago, forming the synth-free Grandbrothers in Dusseldorf only a short while later. Pairing Sarp's piano skills with Vogel's talent for building the formidably intricate mechanics with which he exploits his partner's instrument and also designing its software, Open explores dimensions at which their debut, Dilation, only hinted. On stage, Sarp works at his ivory keyboard while, from behind his computer keys, Vogel live-samples his partner's notes, triggering further effects with the aid of homemade apparatus that physically manipulate the piano's strings and body. Live, the inventive contraptions at the heart of their work provide a physically astounding and visually astonishing display, so it's no wonder their music was once memorably described as "open heart surgery on a grand piano." Their performances underline the complexity and vigour of their work, bringing their love of techno and club music to the fore. As Sarp points out, "We don't only make music for listening to, after all. As much as we enjoy playing concert halls with the audience seated we also love to play at sweaty clubs where people are standing and dancing around us."
