It seems there's been a mix-up in your request. The original biography provided is for GWAR, an American heavy metal band, which does not align with the artist name you've mentioned, Cornelius Carnage, who is presumably a DJ/electronic music artist. Unfortunately, without the correct information or context for Cornelius Carnage, I can't provide a rewritten biography that focuses on their electronic music career. Could you please provide the correct details or clarify the artist's background and contributions to electronic/dance music? This will enable me to craft a concise and engaging biography that meets your specifications.
