Wikipedia:Articles for deletion/Erdling
the German Wikipedia article https://de.wikipedia.org/wiki/Erdling_(Band) here has a lot more references and also indicates that their albums have charted on the German national charts which would be a pass of  criteria 2 (only one criteria needed). It's a weak keep because I don't know much about German music sources or German charts, imv
