Monday was a big day! Of course, we had our intimate acoustic performance with Neon Trees at the Intersection (photos and videos are on the way). And, Maroon 5, Neon Trees, and Owl City rocked the Van Andel Arena! Now, the show got cut short, due to Adam Levine's laryngitis, and I think I know how he ended up with it. He was gallivanting around downtown GR in nothing but a t-shirt! See the pictures after the jump!Ok, so maybe that's not the real Adam Levine, but it's close! And look at him sporting his Channel 95-7 shirt!
