Of all the guys who played Woodstock, how many of them are still soaring high along with Santana? Hell, how many of them are still alive?
Santana knows what time it is. He has for the last 20 years. This is why Supernatural was the massive record it was. And nobody else has followed suit, even though he clearly laid out a template with a treasure map and an answer key on page two.
Santana is no idiot. He's one of the smartest guys in the biz.
