Tosca is an electronic music project of Richard Dorfmeister and Rupert Huber. It is Dorfmeister's second such project, the first being Kruder & Dorfmeister, started in 1994. Tosca's first album, Opera, was released in 1997 with G-Stone Recordings. Richard Dorfmeister and Rupert Huber first met in school, and began experimenting with tape machines, Indian music, and poetry lyrics, under the name of Dehli9. After school, Dorfmeister and Huber went their separate ways: Dorfmeister began producing and DJing with Peter Kruder, and Huber worked in the experimental music scene.

In 1994, Dorfmeister and Huber released their first 12", entitled "Chocolate Elvis", on Kruder and Dorfmeister's G-Stone Recordings.
