It can't be said enough: be cool when you're at a show! You're not the only one there. Lifehacker has provided their guide on "How Not to Be a Jackass at Concerts": don't scream out requests, don't heckle, and shush when the band is playing!
Check out their guide and if you have more concert tips, hit me up on Twitter @mikejonesradio. I have one: don't complain about how the band used to be good. If you don't like them now, why are you at the show?! Stay at home.
