spazntwitch got me the right link (so much for my earlier fortune).
I believe that the "problem" is that you could hear the "singer". I would more suspect they had the worst sound=system ever. Way under-amped and outdoors. There are numerous bands with singers that can't sing (best represented by "scream-o") but they hide behind the loud, uncreative and pounding drums and other instruments that are poorly played or even played well but too loud to really discern.
