Yeah, I remembered that after I posted. Oops!
There’s a great channel on YT, Rick Beato’s, where he somehow has access to the actual separate tracks of a lot of classic rock songs (and a lot of newer ones), and he breaks the songs down, called “What Makes This Song Good?” (He has connections in the industry, and was involved for some years). He has a great interview with Frampton, and he just posted one with Larry Carlton, one of my favorite guitar players (ie, the solos on Steely Dan’s “Don’t Take Me Alive” and “Kid Charlemagne”, amongst others). He also did a wonderful, very informational breakdown of YES’ “Roundabout” using the separate tracks from the actual song.
