I think he is extremely talented, and obviously imprints his personal style onto everything he does.

I have seen/heard many players fill in what should be a space with continued runs up and down a keyboard, glissandos, and waterfalls . It works sometimes, but not between every bar of music or true phrase of melody. It was a common trait among old cleveland-style accordion polka players. Using it over and over in the same song doesn't make it sound better, and I totally agree with Mark in saying it clutters up what are supposed to be simple melodies written with the intent to be played as such.

When I played mandolin and guitar with a band in the early eighties, I played with a style to make pretty songs sound just that. A former band member of mine always said that playing a thousand notes per second is not the only definition of a good player. I did that when required for some bluegrass tunes however.

Around the same time, I once went into a guitar store and was playing some country licks with slides and bending notes when the owner came to me and said" It's so nice to hear someone come in and play like that after spending the day listening to kids playing distorted metal styles all day long". That was something that stayed with me to this day.
