To take you back a hundred years or so, one of the best guitar solos that I've seen Prince do was at Park West in Chicago during the second leg of the "Dirty Mind" tour.
The shows were more loose then and Prince had just started playing the famous Tele that everyone knows today (he use to play and old Fender with a mirror pickguard). On this particular song though, he played a red heartshaped Telecaster (cut up by Knutt Koupee no doubt) and did the song "Crazy You". At the end of the song they started a vamp section and Prince went into this amazing guitar solo. I haven't seen that guitar or heard that song since. Oh well, long live the memories.

Man...there's a lot of Hot solos PRINCE has done in all of
the CHi-town shows i went to.
Most people would probably pick Purple Rain cuz he
would extend that one out to ETERNITY!!!

But i remember him doing a great solo bit with HEAD during
the early 80's period.
OH yeah...and what he did on WHY YOU Wanna Treat Me So
Bad with DEZ...still kicks my BUTT!!!

i'm trying to think of more...If i had a HAREM from the
LOVEsexy Tour is cool and BAD.

The promotional (live) video for "Take Me With You"

Another Chicago show...

The post-Oprah taping show at the Park West upon the release of Emancipation. He did a bass solo (during "Sleep Around") for a few minutes with his leg over the neck while hopping on one leg. I was about 3 feet away from him and couldn't believe he could play such a good solo while having his body contorted like that.

It was unreal.
