when you say 'solo' do you mean guitar breaks as opposed to guitar-based instrumentals like 'Surfing with the alien'?

fave breaks -

Elliot Randall on Steely Dan's 'Reeling in the years'
Dave Gilmour on 'Another brick in the wall'
the solo on Jerry Rafferty's 'Baker street'
the sitar bit on the Dan's 'Do it again'
all the breaks on Satch's 'Big bad moon' esp the slide part.
Albert Lee on 'Country Boy' esp the intro
all the solos on Molly Hatchett's 'Boogie no more'
'Spirit in the sky ' the original version - I love the tone
