Yet the opening Allegro seemed unsettled and sometimes in too much of a scurry; the Finale needing more savagery from all involved as the composer ripped into Stalin's favourite folksong.
Valencia's cadenza was the emotional heart of his interpretation, thoughtfully pursued.
Stravinsky's Pulcinella suite was an adventurous choice, a work that, with all its major and minor chords, was almost as radical for 1920 as the Rite of Spring had been seven years earlier.
Brio abounded and the many solo turns, crowned by some lustily bucolic fiddling from concertmaster Hilary Hayes, augur well for our orchestras of the future.
A shame though that we won't be hearing the orchestra's September concert, a Christchurch-only event.
