I was looking for versions of this song as a singer I am working with wanted to do it and I ran across this smokin;' version.
You could be marveling at Pat Martino technical prowess in light of Martino having suffered a severe brain aneurysm and underwent surgery after being told that his condition could be terminal. After his operations he could remember almost nothing. He barely recognized his parents. and had no memory of his guitar or his career.
Or listening to Mingus Miles Davis alumni John Scofield as his years of experience surfaces as he rips those changes apart.
For me it is the way Joey DeFrancesco really builds his solo to fever pictch...wow
