Yes there are people who haven't heard him perform. Not everyone is lucky enough to still be a student at MSU. Great, he played Rick's a few times. But he was on tour with Dave Matthews recently, and is touring with Kenny Chesney this year. He's also played with Buffet some. They're not exactly a bar band.
So give it a rest. They got a band that people have heard of, have heard on the radio, and will be playing in NFL stadiums this summer. Wanna keep your hippie cred? Go to Dave's that night. But remember, I'll still look down on you because it used to be a real hippie bar. Not a fratty sports bar with bands people think are cool because they wear knitted toboggans and smoke cloves. You had crawl to escape the cigarette smoke, you could escape to the porch to get stoned, wells were 75 cents, there was a 50/50 chance you'd get your drinks because the waitress was high as a kite, and the only tvs were a 13 incher behind the bar and a huge wooden box set. And before my time? I bet it was even scuzzier and people thought the music was better.
So go sell your snobby **** somewhere else. He's gonna draw a crowd.
