DEMO Jimi Hendrix - 1983... (a merman I should be)

Uploaded on May 30, 2009
This is one of a few tracks from one of Jimi Hendrix's unreleased albums. The album is entitled New York Mist and is comprised from tracks, acoustic and electric, which he recorded in his New York apartment in 1968.

Cool!

I believe I have the lossless files of it somewhere if anyone is interested. PM me and I'll look for it.
