I love listening to Hop Along, an indie folk-rock band from Philadelphia.  Have you heard of them?
I have no idea who they are! but i always love hearing new music, are they a recently new band?
No, they are a band that started in 2004.  Frances Quinlan's was the main acoustic player and started a freak folk solo project known as "Hop Along, Queen Ansleis".
Sound great, what is their best song? like their main track?
Their best song is called "Wretches" in 2009 and "Get Disowned" in 2012.
