Welle:Erdball (often abbreviated as W:E) is a group from Germany. The heavy use of the Commodore 64's SID sound chip makes their sound instantly recognizable. Their sound is reminiscent of electronic music pioneers Kraftwerk.
The name literally means "Wave: Earthglobe", and in fact comes from a German radio play called "Hallo! Hier Welle Erdball!" (Hello, this is wave earthglobe speaking!). Their logo is a rotated logo of the former East German motor company VEB Sachsenring, which built the popular Trabant car.
Welle:Erdball has been a part of the demoscene and produced several musicdisks and other productions over the years. They also gave a live performance at Breakpoint 2006.
