SO. AWESOME. And true – but only for up and coming/new bands. Obviously, most of us love hanging out longer to listen to our classic fave bands & would feel cheated if we paid a $45 ticket fee and they played 4 songs in 20 minutes.
But nowadays, and especially when you’re just another band in the middle of a bill w/5 other nobody bands trying to scratch out a musical living, it’s very good advice and, hopefully, leaves ’em wanting more.
Kinda like only french kissing on the third or fourth date. Keep a little mystery going for as long as you can…And keep it SHORT, HOT and PASSIONATE.
