PLAYING  his alto and soprano saxophones with a rampant, joyous attack like a contemporary Sidney Bechet, from the very first notes Trevor Watts defies his advancing age.

The 80-year-old, a veteran of revolutionary bands like Spontaneous Music Ensemble and Amalgam from the 1960s and 1970s, rises to a seething ascent as he kicks backwards on reaching each sonic summit.

Veryan Weston’s chiming, intricate piano and the artistry of  John Edwards’s bass and the mallets of the subtle, ever-inventive drummer Mark Sanders beat out a thunderous salute to Watts’s eight decades.

After Weston’s ruminative, echoing solo conjures a sudden tenderness, followed by Watts’s volleys of triumphant riffs, the sound fades.

In the silence, there’s time to marvel that a man now in his eighties, with his shock of leonine hair, can still blow his horn with such outrageous fire, zest, youth and optimism.
