I saw Dashboard Confessional on December 18th at Lincoln Hall in Chicago, IL. I've been listening to them for a while and they're one of the bands that really got me in to music, but this was my first time seeing them live.
I thought I'd recommend a couple of my favorite EPs. EP technically mean "extended play" and usually has up to 36 minutes. It's longer than a single, but shorter than a full length LP. I like EPs because they are short and to the point and tend to have good songs (and not a lot of filler).
