I saw Al DiMeola of Return to Forever jazz-fusion fame (Chick Corea, Stanley Clarke, Lenny White) on a solo tour for his "Land of The Midnight Sun" album back in 76 or 77. I grew up on the exaggerated stage theatrics of most of rock's lead gutiarists. So Al was a revelation.
When he began playing just the rythm line for "Suite: Golden Dawn" - I just stood there mouth agape. He was tearing it up but Al just stood there shredding with all the enthusiasm of somebody reading a newspaper.
By the time he was into the solo's for that song - I was firmly convinced the dude was from another planet.
