The Lumineers came full circle last night as they headlined the second night of the 2013 XPoNential music Festival Presented By Subaru with a performance at a packed Susquehanna Bank Center. Just last summer, the Denver band opened 2012's festival on the smallest stage. That was before they toured the world and earned themselves a Grammy nomination. Their quick rise to the top can be accredited to their catchy, sing-a-long songs like "Ho Hey" as well as local radio stations like WXPN who gave them a shot on the air.

Also on the bill were local indie favorites, Dr. Dog, who have had a slow but steady rise to where they are now. It was only a few years ago where the band was playing free shows in Rittenhouse Square. Their drive and determination led them to one of the biggest stages in the area with a dedicated fan base that stretches well beyond the tri-state area. The Philly band have a new record coming out this October titled B-Room.

Minneapolis' Poliça are another band who have had a relatively quick rise with their dual drummers and eclectic front woman, Channy. Their first show in Philadelphia was the very first show(and they were the first band to have played) at Union Transfer, where they opened for Clap Your Hands Say Yeah!. Since then, they have played out several sold out shows themselves in Philadelphia and played to a packed side stage last night. With a new album coming this fall titled Shulamith, the band is bound to take it to the next step.

All three acts are products of support from local independent non-commercial radio stations like WXPN. Without such support, one can only wonder where they'd be.
