And what you may find is on a lot of those 80s Heavy Metal songs, the guitar solos were not done by the band members, there was a Heavy Metal version of “The Wrecking Crew” as well.
Steely Dan had their own version, they just kept bringing in musicians until they got the sound Donald and Walter wanted. There are some interesting videos on YouTube about this process.
Even as good as Aerosmith’s guitarists were, the great solos on “Train Kept a Rollin’” (1974) were performed by session players.
