I have a couple long plane rides coming up and I want to download some music to my phone that I can listen to in airplane mode. I figure this is the perfect chance to listen to new music that I'm not familiar with. Can anyone suggest some good under-the-radar artists I might want to check out? Tastes run from alt-country to roots and rock. No pop, top-40, metal, synth, emo, etc etc. Turn me on to someone I might have missed. Thanks!
