Really tough to chose one in particular. Off the top of my head, some truly outstanding solos are:
Pink Floyd - Comfortably Numb
Extreme - Get the Funk Out
Oasis - Don't Look Back In Anger
Steve Vai - Bad Horsie
Stevie Ray Vaughan - Texas Flood
Guns N' Roses - Sweet Child O' Mine
Nirvana - In Bloom
Metallica - Blackened
Two in that list will raise eyebrows but I think they are spectacular.
