In the opening Allegro, the musicians happily ignored a ritardando to sustain the frenzy, while the Scherzo that followed let loose a whirlwind of flying quavers.
The second of two more relaxed episodes allowed the musicians to enjoy the composer's almost jazzy rhythmic ploys and the Andante was a frank love ballad, instigated by Florian Eggner's rapturous cello.
The three brothers had the stage to themselves for a Beethoven Ghost Trio that bordered on the terrifying.
The slickly navigated first movement was airborne and zooming within a few notes followed by a dramatically charged Largo assai ed espressivo that ranged from thunderous crashes and roars to mysterious, spooky whispers.
The presence of Amitai Grosz enabled the inclusion of Anthony Ritchie's Oppositions that fitted in well with the other volatile performances of the evening.
Finally, Christoph Eggner revealed that the encore would be intimate and beautiful. It was all of that and more. The Andante from Brahms' Third Piano Quartet was a soulful song of entwined textures and heart-stopping shifts from major to minor.
