I'm ashamed of the fact that I've been completely ignorant about the New Amsterdams, the band of Matthew Pryor who was the singer of the Get Up Kids. Big thanks to last.fm Neighborhood player, which made me aware of this great band, that everyone who likes the Get Up Kids will like. (I tuned in to "the Similar artists to Blackpool lights" for an hour and found a couple of interesing bands that I didn't know)
There appears to be a couple of albums out available, and I picked the one Worse for the Wear as a start and purchased from iTunes store. It rocks! I will buy other ones every week, to fully enjoy each one.
