The Rifftides reader whose reply to a comment included a link 
to Prince playing something labeled The Greatest Guitar Solo Ever might consider a meeting between Jimmy Raney (1927-1995) and Attila Zoller (1927-1998). I would not claim ultimate greatness for this performance, only mastery of the instrument, taste, imagination, wit and enormous satisfaction. The piece is Cole Porter’s “I Love You.†I have no information about the location or year. According to Raney’s hint at :03:41, it may have been around Christmas time. Zoller is on the left, Raney on the right of your screen and speakers.
Have a good weekend.
