Ok, not really a mashup, but I found these mp3s of a session recorded in 1969 by Johnny Cash and Bob Dylan. (Many thanks to Between Thought and Expression for making these available.)
I have to tell you that my four-month old iPod has re-awakened a love for music. I probably do more to seek out new bands and am listening to new bands or rare tracks at a much higher rate than at any time since my early 20s (must… fill… up… iPod).
To see what I listen to while slaving the days away, just check my audioscrobbler account (or click Now Playing at right).
np: Doves, Some Cities.
