Since the late nineties, Roc Jiménez de Cisneros and his collaborators have been producing what they call "computer music for hooligans", inspired by geometry, physics, noise, cosmology and rave culture. A vortex of generative basslines, air horns and strangely familiar vocalisations, their music displays a radical and playful approach to algorithmic composition, with works available on Entr'acte, Mego, Presto!?, Diskono, Scarcelight, fals.ch and their very own ALKU.
In 2003 the group started an ongoing series of electroacoustic pieces entitled Punani, built around the implementation of generative techniques and psychedelia in what Kristian Vester defines as Radical Computer Music.
Occasional EVOL members since 1996 have included Stephen Sharp, Rubén Patiño, Miguel Ferrer, Jakob Draminsky Højmark, Joe Gilmore, Anna María Ramos, and Andy Davies. The name of the project comes from Sambucus Ebulus (in Catalan, évol), a herbaceous species of elder with a characteristic foetid smell.
