Blitzen Trapper

As soon as the first notes of Blitzen Trapper's song, Wild Mountain Nation come through my speakers I'm immediately reminded of something: a band, a song, an album. The problem is I can't pinpoint it. I've read of comparisons to The Greatful Dead, Pavement and others, but I don't think that's it. It could be but it's not perfectly clear to me. Is it Steve Miller Band, or Lynyrd Skynyrd, CCR or a combination or someone completely different? I can't put a finger on it, but maybe that's the point, maybe it's their own sound which sounds familiar because it's good. I immediately liked the song when I first heard it. I've heard the cd is one of the best of the year, I look forward to hearing more of them
