I never paid any mind to Jimmy Page's "Death Wish II" soundtrack. I don't recall any Zeppelin fans raving about it either. Then, on his 1988 solo tour for his first proper solo release, "Outrider," Page played a gorgeous instrumental that lasted about two minutes. The playing was pure Jimmy. My friend recognized the piece as Chopin and then soon after discovered it as "Prelude" on the aforementioned soundtrack.
This track made me think a few other great instrumentals, including the two posted here, Ronnie Montrose covering "Town Without Pity" and Mick Ronson's version of "Slaughter On Tenth Avenue."
I love them all and I think another half dozen to a dozen choices would make a great Weekend Mix.
