It's not Nessun Dorma, but.....
This has strings-
I read a mid-'70s interview in Guitar Player and he said that he didn't use a pick, that he had mastered the 'trickery' on guitar. At the time, I took as him being a bit arrogant, even though I had heard Yardbirds, some of his late-'60s music and all of Blow By Blow & Wired. I had his 'Jeff Beck's Guitar Shop' and didn't really like it until about a day before I went to see him sometime between '06 and '10. After hearing it again, I asked my self "What's not to like?". That show was in a relatively small-ish place with an oval, domed ceiling- that should have made it an acoustical nightmare, but the sound was excellent.
I'm not sure if this is hitting me the way it is because it was so sudden or because I have been watching so many videos with music I hadn't heard before.
