Welle: Erdball (often abbreviated as W:E) is a group from Germany often credited with being the pioneers of bitpop. 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.
