Another one of my favourites (besides the one I posted a few pages back) would be Jeff Baxter's solo in Steely Dan's Change Of the Guard. I'd post the video, but some killjoy's gone and taken it offline.

The acoustic one.

Oasis - Live Forever!

I always found Steve Hackett's solo in Genesis' Firth of Fifth to be utterly compelling, moving and just lifts the whole song to new heights... amazingly good solo. Most of the solos he performs on The Lamb Lies Down on Broadway album are equally amazing too. Definitely a very underrated, very talented artist.
