John Lucas

I came across this guy on noisetrade.  He sounds like a mix between Gregory Alan Isakov and John Mark McMillan to me, and it works quite well.  The music is generally quiet, but it does build in a nice way, and he has a very calm and relaxing voice.  I particularly like the chill guitar riffs.  Apparently you can download his entire first album on his bandcamp page, and I would recommend it if you like melodic, folky songs.
