It appears there has been a misunderstanding in the request. Based on the original biography provided, there is no mention of a Belgian electronic or dance music group named Rorschach. The list includes various references to the name Rorschach across different media and contexts, such as psychiatry, comics, a punk band, and more, but does not specifically address a Belgian electronic music group by that name.
Given the confusion, it's not possible to rewrite a biography focused on the music career, style, and contributions of a Belgian electronic music group named Rorschach without accurate information about the group's existence or achievements within the electronic or dance music scenes. If you have any other artist or group in mind, or if there are more details available about this particular act, please provide them for a proper rewrite.
