That’s funny, but honestly, there’s no way that Steve Gadd wouldn’t recognize his own playing on the “out” drum section of (the tune) Aja. It’s not that it’s the greatest drum “solo” of all time, but the style is very uniquely Gadd.
If we look back at our past 30 years , we probably forgot some of the “cool” things we did at our respective employers.
Aja is probably just another “cool” thing that Gadd did. As you note, it’s not 50 Ways. But when you work at that level, “cool” things run into one another.
