Bless Andy Baio:
These are the unreleased demos from Joni Mitchell’s The Hissing of Summer Lawns, one of my favorite albums ever. Unlike the lush arrangements found on the album, these early versions are stripped down to only piano, and acoustic guitar.
He found this rare recording at Big O Magazine which has a bunch of other interesting things up for download (oh look: Loggins & Messina!). Just try to ignore the Japanese girl with the bouncing boobs to the right, and focus on the left part of the page…
