Metal Ping!
So many citations of great guitar solos are listed here that I have to be contrary and consider the other talents. Neal Peart of Rush took drumming to percussionism after John Bonham led the way. Les Claypoole’s bass work is so distinctive I recognize his work instantly when he sits in for someone else. Rick Wakeman’s mastery of all things keyboard. Unique vocal talents of Freddie Mercury, Pat Benetar, Rob Halford and Ann Wilson. Amy Lee is a sonic laser.
My all time favorite guitar solo, though, is the blatantly commercial “Mr. Crowley” done by the tragically taken-young guitar genius Randy Rhodes. He performed it in one take in a fit of pique at Ozzy and asked if that was good enough for him. Astounded Ozzy agreed it was.
My next favorite is Motley Crue’s “Home Sweet Home” as it manages to purposely capture nearly every rock riff cliche’ possible in one song...while still being a good song. That took nads and real creativity.
