Jeff Rosenstock was great, as was Pup, and Modern Baseball. Disney will never be a great place to see a concert though, it was like seeing a punk rock show at a mall. Security seemed like they were being okay to crowd surfers which was good to see. Unfortunately though downtown disney's half marathon chaos likely caused many show goers to miss acts as they navigated alternate parking areas routes.
An acquaintance convinced me to go see "Laura Stevenson and The Cans" in Berlin. This was on rather short notice so I only listened to some random songs before the concert. To be honest: I wasn't sure if I would like it. Stevenson's voice sounded somewhat high-pitched. But I enjoyed every minute of the show. The voice is not so girly squeaky in real. Little but nice talk in between. Having learned to play the accordion, I'm always surprised to see how well this instrument goes along with non-folk rock music. I especially loved those songs. So, if you can, go see her/ them.
