Most of the music I listen to is not heard by many, but is still very good. A lot of bands, especially those that have been around a while, have very rare music like demos, B-sides and one-off covers. I think that a lot of this is as good, or better, than the stuff that hit mainstream.
so, what rare music do you have by your favorite bands? here are two of my favorites:
World by the Foo Fighters. Mellow song, good ballad.
