I've discovered all kinds of music and done all kinds of music over the past 40 years, from playing tango with Piazzolla to all the different bands I've had.

There are a few things that I will hopefully be credited for as a pioneer. One is my four-mallet playing. Another one is the starting what was first called jazz rock in 1967 when I started my first band, later became jazz fusion by the 1970s.

It keeps me in touch with younger musicians who are constantly saying, 'Have you heard this new artist, or this new guitar player?' It keeps you reaching.

I was surprised when I finally moved to Boston and the East Coast, to discover that there weren't that many vibraphone players around. And I was the only one playing with four mallets.

Most people learn to improvise on their own, listening to records, endless hours of noodling on their instrument in the bedroom with all their spare time. That's traditionally how people learn.

Improvising musicians are musical travelers, voyagers. There is a freedom to wander the musical landscape.
