Really?
you have to ask?
There are hundreds of them.
I played a festival in the summer, in Leipzig, with over 200 bands on and not one of them has ever been in the charts, although New Model Army and Tangerine Dream might've been, I'm not sure. And that's just one festival.
On the circuit we tour in Europe we come across bands that have never charted everywhere we go: The likes of Balaam and the Angel and Soft Kill for example.
