Sonja Moonear (born Sonja Mounir, 1978) is a Swiss DJ, producer and sound designer who is one of the most significant figures in contemporary minimal house and techno culture. She began playing piano at age four and studied classical music before discovering electronic music through KLF, acid house and the Swiss underground rave scene. In the mid-nineties she organized events in Geneva's squats alongside the Mentalgroove crew. She abandoned her piano studies for a Roland R-8 drum machine and turntables, and secured a residency at Geneva's Weetamix club in 2002 alongside Luciano. She has played b2b with Ricardo Villalobos at Panorama Bar, and released on labels including Perlon and Karat. She runs her own Ruta5 imprint and is also a sound designer for Swiss-French television. Her sets are known for their enormous wealth of ideas and deep, hypnotic character.
