I've been trying to put them all together since Ian started this, but I could never mention all so here are a few {BTW, I listen to a wide range of music)

The Beatles of course, I remember seeing their first performance in the US on the Ed Sullivan Show.

Allman Bros, Moody Blues, Yes, Al Dimeola, John McLaughlin, Steve Morse, Weather Report, Billy Cobham, Stanley Clark, Rickie Lee Jones, The Dregs, Eric Clapton, John Mayall, Savoy Brown, Stevie Ray Vaughn, Kate & Anna McGarrigle, Kate Bush, Joanie Mitchel, Emmylou Harris, and more.

It would be impossible for me to actually come up with a favorite.
