Stan is just too talented to play out of his league. People who know his music, expect more. Once you give people your best, they expect nothing less.
Music is no different than any product you buy. When you buy something of quality, and then the next day, its cut with additives and sold at a higher cost, you sacrifice a loyal fan base to gain only fad consumers.
Its very difficult to diversity great talent, to a fad level of music; especially if people see you as a single artist.
Say the word: Prince, Santana, Joe Satriani, Robert Cray their music it consistent to the genera.
Herbie Hancock did Rockit and it was a successful Hip-Hop cut but for those people who would expect more of this kind of music from Herbie, would be hugely disappointed because he's a Jazz man.
As for Stanley, he's in that circle of distinguished musicians as well, so maybe he should just stick to playing quality music (which he is now... Victor and Markus keeping him on the one for the 80's was a bad trip).
If you asked me, there was nothing wrong with RETURN TO FOREVER, in the first place.
