It seems there's been a bit of confusion in the request. Flattus Maximus is indeed a character from Gwar, an American heavy metal band, and not directly associated with the electronic or dance music genres. Gwar is known for its elaborate science fiction-themed costumes and satirical themes rather than electronic music production. As such, Flattus Maximus doesn't have a music career, style, or contributions within the electronic or dance music scene to detail. If you have another artist in mind who is active in the electronic or dance music genres, I'd be happy to help rewrite their biography.
