The new EP by German duo Grandbrothers is a collection of remixes and re-interpretations of their standout track Bloodflow. The remix by UK producer Lone was introduced last autumn but theres brand new tracks to be found here by German techno electronic vanguard Christian Löffler, everyones favourite new IDM producer Brainwaltzera and new Permanent Vacation signing Aera Grandbrothers are the sum of unique parts: progressive Swiss engineer/mechanic/sofware designer Lukas Vogel and German-Turkish pianist Erol Sarp. Their second album Open twins Sarps piano skills with Vogel’s talent for both building the homemade intricate mechanics with which he exploits his partners instrument and also designing its software. Sarp works at his ivory keyboard while, from behind his own computer keys, Vogel live-samples his partners notes, triggering further effects with the aid of DIY electronic apparatus that physically manipulate the pianos strings and body.
