look what I found! for those of you like me who remember the good ol' days of MTV Unplugged, or the later and also very good VH1 Storytellers, Stereogum has a similar online series called Decomposed featuring up and coming artists performing stripped down versions of their songs. and some v. pretty photos, if I might add.
here are links to three of them:
the Soft Pack
Friendly Fires - who interestingly enough is the first non-American band to take the Decompressed stage
the lovely School of Seven Bells - who you might know through their single "iamundernodisguise"
