The MONO recording of Jimi's second album, Axis Bold as Love, was reissued on vinyl a couple of years ago, but I haven't gotten to picking up a copy. The mono version is slightly different, and is supposed to be the best of them all. I wish I had bought the mono one when it originally came out - but everybody was hooked on "stereo" in the 60's - so the original is rare, and goes for $2000.00 if you can find it!
