Dr. Nexus is world wide well known for his punk ass attitude which pretty much already there describes his approach on "music".
The set-up to pull this off is in a constantly changing mode. It is based on several open source hardware elements like synthesizers, solar sound moduls, sampling moduls, etc as well as different electronic rythm devices.
To describe the sound of dr. nexus in human vocabulary you could call it "Hyper spasms of beats and noises" or something like a "mental miniskirt".
He works alone and in an endless line of collaborations.
