I'm certainly not trying to dog Prince, I'm an admirer, but I'm going to stick up for one of the most overlooked guitarists, Wendy Melvoin who I think played a fair bit of the guitar on his studio records once she joined his group, and had at least a hand in the iconic (in my mind) "rhythm" guitar part in Purple Rain. The outro solo is of course pure Prince, and one of the best sparse solos I've ever heard. Part of the reason Prince doesn't immediately come to mind with a lot of people when people think of guitar players is that he was such an accomplished multi-insrumentalist, and at least thinking back to what I can remember from the 80s, many of his songs that got on the chart didn't feature guitar prominently. I didn't realize how accomplished he was until I saw his performance on While My Guitar Gently Weeps a few years ago. I've never done a deep dive on his catalog because by-in-large his music that got on the radio/MTV wasn't my cup of tea, especially at the time, with maybe the exception of Purple Rain. No doubt the man was an extraordinary musical genius, but the extent of his skill on guitar was one of the best kept secrets, even among guitar nerds, for a long time, which is likely a tribute to his skill as a composer/arranger. Moar Guitar is not always better!
Up here in the woods I don't have the bandwidth to stream the video you linked right now, big thunderstorms in the area and it'll take a while for everything to get straightened out, but I'll come back later and check it out. I'm a latecomer to the Prince as guitarist bandwagon.
P.S. It's much more fun to talk about guitar/guitar players than Trump and politics.
