Yes, I'm posting this again, but it is such a great performance by both the lead vocal and the lead guitar. The guitar solo after ~2:40 is perfect and remains among my favorites, if not the favorite, at least at this moment

I remember when I listened for the first time to this song. I don't know how I came about it, but I got to it and started listening while doing something at the same time. The first thought was, wow Wilson Pickett has such a great voice, sounds much better than The Beatles. The amazement, however, was mild, but then all of a sudden, guitar solo by Duane Allman started! I immediately left whatever I was working and the reaction was goosebumps and whooo(next minute or so)ooooa, it
blew my mind. Many guitar players have copied the style, but at the time it was groundbreaking and today, to me, it sounds better than the copies, especially on the emotional level.
I (like to) imagine Eric Clapton must've felt similar when he first heard it, because the story goes that he was driving a car and heard this song on the radio. As soon the guitar solo started he pulled over and listened to it and after that he went to call some people to find out who was the guitar player.
This song was a breakthrough for Duane Allman, he got a call from Clapton to work on the recording of "Layla and Other Assorted Love Songs" and the things picked up with the ABB. I still get the goosebumps when listening to the solo with the volume cranked up, and still feel the need to leave whatever it is I do at that moment in order to listen to it
