- It's geeky to wear a T-shirt you just bought at the concert you're attending. Besides, your mother would want you to wash it first.

This would seem to be Gundersen's reinterpretation of the "Don't be that guy" rule from PCU, in which Jeremy Piven's character chastises, "What's this? You're wearing the shirt of the band you're going to see? Don't be that guy." Only with laundry. And Mom. Not cool, dude.

- If you must wear a Metallica T-shirt at a Metallica concert, make sure it's from three or four tours back.

Not only does this break the aforementioned "don't be that guy" rule, it also creates the false caste system that people who actually went to see Metallica in 2003 are somehow better than "newer" fans.

- Unless you're 8, a High School Musical T-shirt will draw snickers. However, a Schoolhouse Rock! shirt is kitschy.

But if you wear it to a Blind Melon show, are you "that guy"?

I guess it depends on whether post-Shannon Hoon death Blind Melon is a different band. (Let the arguing commence!)

A Nirvana T-shirt at a Foo Fighters concert is too obvious; Melvins, maybe. A Screaming Trees shirt at a Queens of the Stone Age concert or a Green Jello shirt at a Tool show will reveal you as a fan with roots.

I wholly disagree with this idea, because it violates a corollary of the "don't be that guy" rule that I like to term as "don't be that person who is trying to have 'cred,' even though the shirt bestowing such was probably purchased at Hot Topic anyway."

- Don't wear a Woodstock or Live Aid T-shirt unless you actually attended.

- Even if you were there, don't wear a Woodstock '99 T-shirt. Why admit it?

Because comedy = tragedy + time? Hey, it's been nine years. (Really, when was this thing written?)

- Never wear a Gary Glitter T-shirt. If you don't know why, look it up.

OK, this is probably good advice. Although I did hear "Rock & Roll Pt. 2" at a sporting event recently, so who knows, his ironic rehabilitation could be just around the bend...

Concert tour T-shirts crank up the style [USA Today]

Dan Aquilante, New York Post
Top show: True Colors tour feat. Cyndi Lauper, Joan Jett, and Rosie O'Donnell ("I guess that's when you go for beers"—stay classy, Aquilante! )
Head-scratcher: Coldplay's MSG date for best free show? Out of every free show in New York City? Where there's one daily during the summer?
Robert Plant/Alison Krauss mention: Yes ("Best country concert... a marriage of harmony")

USA TODAY
Top show: Kenny Chesney ("Chesney is determined to deliver: After his foot got trapped between the stage and a hydraulic lift while making his entrance in Columbia, S.C., he performed for nearly two hours before seeking medical attention.")
Head-scratcher: What, no mention of the huge margaritas at Chesney's shows?
Robert Plant/Alison Krauss mention: Yes ("among the most distinctive and celebrated singers of their respective generations"

Ray Waddell, Billboard
Top show: R.E.M. ("People are excited about R.E.M. because R.E.M. is excited about R.E.M," says indie promoter Seth Hurwitz.)
Head-scratcher: The Hinder/Staind/3 Doors Down tornado catalyst as one of the entire touring world's top five tickets? Really? Perhaps he was just being nice since lawn seats are only $25.
Robert Plant/Alison Krauss mention: Yes ("Another one of those 'catch it while you can' tours")

Seattle Times
Top show: The big Sub Pop extravaganza SP20, duh.
Head-scratcher: Hey Seattle-based journalist, I think the reuniting "originator long disbanded" that you're talking about is Green River, not Mudhoney. (I know, I know, it's tough waiting at all for new music from them.)
Robert Plant/Alison Krauss mention: No—but that may only be because they're not yet scheduled to play Seattle this summer.

Jim DeRogatis, Chicago Sun-Times
Top show: DeRo's shows are listed chronologically arranged, so first up is Kanye West's Glow In The Dark Tour ("raising the bar once again for live hip-hop")
Head-scratcher: No real stinkers here, although I would like to say that I'm 100% jealous over Stevie Wonder's free show at Taste of Chicago—and the mere mention of the food fest is making me hungry to boot.
Robert Plant/Alison Krauss mention: Yes, albeit a lukewarm one ("this is as close as we're going to get to Led Zeppelin this summer"—awww.)
