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.

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.

I know of musicians who have played together for decades who hate each other. The Modern Jazz Quartet for one.

Without doubt, the foremost band for decades has been the One O'Clock Lab Band at the University of North Texas. Through its many incarnations and under various leaders, they have demonstrated the highest qualities of musicianship imaginable, plus a willingness to balance their big band tradition with creative exploration. Astounding ensemble work, insightful interpretations of the arrangements, imaginative writing, and above all, a loving attention to musicality . . . these people play beautifully.

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.

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.

But if you listen to great piano players, both classical and jazz, theres a huge range of dynamics and colors and emotional expression thats possible with the instrument.
