Looking for a weekend concert in Dallas without the usual crowd? You know, the frat boys, the weightlifters and the vacant groupies. You're looking for a concert where people don't shove each other around or talk through a band's set. Normally, we'd laugh and tell you to find that in Denton, but on Friday, you'll get your wish with less mileage as Trees hosts indie favorites Pedro the Lion and John Vanderslice. Both bands feature smart, earnest takes on the lighter side of emo-pop, which basically means the usual Dallas crowd won't be in attendance. Take advantage.
