First up will be...
"Eavesdropped in intimate moments"
I saw a request for this on one of the pages.
It is a lot of prince improvising on the piano, including developing the track "So High" (aka "Purple Music"), also the final version of "So High", Prince version of "Baby You're A Trip" (from Jill Jones album).
