The following appeared in a recent Guitar World interview with the great Rocco Prestia from Tower Of Power:
"Looking back over your 50-year career, do you have regrets?
Sure—I should have involved myself more in the business and leadership side of TOP, instead of just going along for the ride. I might have gotten into writing sooner and helped with decisions on some of the directions we went in. I also should have learned to read music. Not being able to read handcuffed me drastically, because there’s so much work that can be had with that one skill. I gave up on it early; I just didn’t have the patience required, and then my career got underway. I’ll follow chord and even notated charts as best I can, but best for me is when someone calls out the changes."
