The Hanbury Ballroom, Kemp Town, Brighton, played host to an evening of "garage electronica" and "bedroom experimentica".
About 80 people attended what was thought to be the region's first "laptop jam", with performers using laptop computers to improvise music and images live on stage.
The jammers download images, music and video footage from the internet or create original material, which is then edited and prepared for performance. The organisers are hoping the event, which was broadcast live on the web, will be the first of many jams.
