If you enjoyed War on Drugs, here are a few more newish jam bands that you might want to sample. Most have come to my attention by either Pandora mixes,
WMWV (you can pick this great station up clearly across much of the lake), or the music the lifties play at the Profile chair...
Pigeons Playing Ping Pong
Spafford
Umphreys Magee
Big Something
String Cheese Incident
Railroad Earth
