The two that immediately came to mind were:
The first solo in "Comfortably Numb" isn't mentioned very often but I think Gilmour did a masterful job of conveying veiled pain on that one. It sort of sounds happy but there's clearly an underlying pain in it. However, the second one just OOZES pain and anguish. Actually, there are many moments on The Wall that express pain, sadness, estrangement, etc. (such as the hopeful, "Everything will be OK, right Mum?" sound of the organ when it first comes in during "Mother"). The Wall is hard to beat as an expressive, emotional album.
And to go the opposite direction, I think the main guitar riff as well as the middle solo in The Allman Brothers' "Jessica" simply sings with joy.
