Those are the kinds of 'general truths' that are 'specific lies'. Obviously, it depends on the gig. There are hardly any jazz gigs where that statement would be true. In a classic coffee house setting, mightn't a singer/songwriter with an acoustic guitar be better suited to the gig than some guy whaling away on his Tyros 3 (in fully orchestrated compressed CD mode ).

We have to stop using general statements to make our point. Somebody is liable to believe you.
