Alex Lifeson (Rush) on Xanadu, the live version from "Exit Stage Left" - no shred here but still technically difficult involving, as it does, pinch harmonics and volume swells.
David Gilmour, particularly from Pink floydd's Division Bell. Very melodic, beautiful.
Mike McCreedy (pearl Jam) esp. on Ten e.g. Garden. Borders on shred on the song why go.
