I don’t remember how I came across Old Blue Bus, “an audio blog with no particular destination.” Might have been through Whole Wheat Radio. Might have been when I was trying to figure out where I’d downloaded “Little Bird of Heaven,” by the Reeltime Travelers. (Great song, though I still haven’t found it online.)
Anyhow, the guy posts decent quality MP3s of all kinds of good music and seems to know what he’s talking about. Not a bad place to go to hear stuff you probably haven’t heard before.
Update: I should have guessed it (and just did); I got the Reeltime Travelers MP3 through a J-Walk post.
