Though he was initially strongly identified with the avant-garde, Watts is a versatile musician who has worked in everything from straight jazz contexts to rock and blues.

He has only occasionally recorded in freer modes in recent years, notably the CD 6 Dialogues, a duet album with Veryan Weston (the pianist in earlier editions of Moiré Music).

Watts has toured the world over numerous times, run workshops, received grants and commissions, and he has collaborated with jazz musicians including Archie Shepp, Steve Lacy, Don Cherry, Jayne Cortez and Stephen Grew.

As of 2011, he continues to travel and has been touring Europe and North America with Veryan Weston and more recently, with the addition of percussionist/singer Jamie Harris as Eternal Triangle.
