If you find nothing wrong with the way the crowd treated Dylan, you're a waste of air.
You're VERY perceptive! He really IS. But maybe he's just getting warmed up. He hasn't reached 10,000 posts yet. It's the hipster version of Malcom Gladwell's "reps" theory.
Dylan LeBlanc is probably a very talented, young, singer-songwriter. I'm sorry he was treated poorly but that's what DC crowds ARE. Mom and Daddy paid for their massively overpriced, liberal arts educations and they go to places like the 9:30 club to do three things:
1.) Mark time.
2.) Talk on their cellphones.
3.) Loiter.
Here's a perfect example: They treated Dylan LeBlanc poorly but stood in rapt silence to watch Courtney Love practice her Mel Bay chords for 47 straight hours.
P.S. They also genuflect for Nick Cave, Radiohead, Wilco, etc. basically everyone Pitchfork used to give >9 for but now give <6 for. Hipster DC crowds....discerning they're NOT.
