I first discovered Monsters of Folk through the television show, Parenthood. That show has such an amazing soundtrack, so I'm constantly looking up songs from it. Anyway, I heard Monsters of Folk and immediately loved them - and later found out that one of the talented quartet is none other than M. Ward! It also turns out that the three other guys are also in other bands - namely Bright Eyes and My Morning Jacket.
M. Ward, Jim James, Conor Oberst, and Mike Mogis started their folk/indie band in 2004 after touring together. They realized they worked well together and, as time permitted, released an album in 2009.
Check out their website and Myspace.
