Or maybe THE PROBLEM is the musical cultural acceptance today? I mean if the audience is forgiving or worse 'indifferent', then the band/singer will never get called on it. Like others have stated before, if the singer is OK, then the band will probably get by. If the singer sucks, in my mind, that is bad news for the future of the band. BUT, if audiences tolerate sucky performance... then I don't know what to tell you.
