Lately I've really enjoyed the following
Metallica's - To Live is to Die, Creeping Death, Unforgiven
When I think of guitar solo's KH is the 1st person who comes to mind
David Gilmour - On an Island - ultramelodic solo
Enslaved - Fusion of Sense & Earth - fits the song perfectly
GNR - Estranged, Sweet Child O' Mine - Slash was so good at one time
Led Zep - Dazed & Confused - One of my all-time fav songs, great solo caps it off
