The Killers: Unless you're a lover of their first two albums, (and I'm talking about knowing more than three songs), class is the best choice based on the fact that you won't look stupid when yelling out the wrong thing.  

Chris Cornell & Timbaland: Class can wait.  With Chris Cornell's hypnotic voice and Timbaland's insane beats this concert isn't one to miss.

Jonas Brothers: Not unless you're comfortable around screaming tweenagers and bubblegum pop. 

Katy Perry: Though and up and coming superstar, this pop singer should give a performance worth missing class. Based on her many performances of "I Kissed A Girl", who knows how outrageous this concert will be. 

Dane Cook: Even though he can't sing, (but believe me he's tried), Dane Cook's overused material and repetitive mention of anything revolving around sex, makes his show graphic and somewhat repulsive.  These performances are limited since he is trying to become a serious actor, but his performances are more enjoyable for free on YouTube than at a venue forking over the $80.00.
