21st Century (2015). Composer John Frith has written a new solo virtuosic work for bass trombone with piano accompaniment of about 3 minutes in length for soloist Jonathan Warburton. "I have written a number of pieces (over many years) for Jonathan Warburton who also commissioned `Sons of Thunder' in 2015. Jon's gift for musical `acrobatics' gave me the idea of creating a short, high-energy work that would give vent to his exceptional range and flexibility. The central section is muted and relatively calm but it is not long before the music builds and the opening material returns. A solo cadenza creates a welcome calm interlude before the storm gathers once again as the piece builds to a momentous fortissimo before grinding to a thunderoushalt! 'Sons of Thunder' is the nickname given by Jesus to the apostles James and John, possibly reflecting their lively characters__I'm guessing that theirs were not too unlike Jonathan's ebullient personality!" -the publisher
