i can't say enough good things about these guys. We had their 5 piece polka band play our wedding reception and they absolutely made the experience. They played all types of music--in polka style! I was a little hesitant how much polka music my guests would enjoy but everyone loved Polkadelphia's engaging attitudes, fun demeanor and upbeat music. They even played some music in non-polka style just to mix it up a little. Polkadelphia got the crowd going with some toasts in between sets as well. Dan was our contact and he was very fast to respond, was super accommodating and even learned a few new songs for us. I recommend them for any German, Polish or otherwise awesome themed party!
