yeah, that's me. my money comes from work with my band and all my sales happen at those live shows. the stuff online is mostly unmastered rough cuts. they're free, and i'll mail out CDs or email songs when people ask for those versions. i'm glad you liked it.
WRLT Lightning 100 is another radio station (based out of Nashville) that has great live performances from lesser-knowns. this one is from Delta Spirit:
