GBSR Duo

GBSR Duo – George Barton (percussion) and Siwan Rhys (piano) – combines two of the UK’s finest young contemporary chamber instrumentalists: “a wonderful, adventuresome, sensitive pair of musicians” (Kate Molleson, BBC R3).

Known for their fearless, intense performances, GBSR’s work ranges from the twentieth-century modernism of Stockhausen and Ustvolskaya to music by Brian Eno and Aphex Twin; from the exquisite delicacy of Eva-Maria Houben and Michael Pisaro to the cracked virtuosity of Laura Bowler and Arne Gieshoff. Regular performers at Huddersfield Contemporary Music Festival and London’s Bold Tendencies, other recent performances include Wigmore Hall, Queen Elizabeth Hall, Tectonics Festival, LSO St Luke’s, Walt Disney Hall, Stadtcasino Basel, Festival d’Aix-en-Provence and Darmstadt Festival.

GBSR’s recordings are praised for their exceptional fidelity and variety, whether bringing new depths of appreciation to existing repertoire through benchmark recordings of Stockhausen and Barbara Monk Feldman, or highlighting new works in premiere recordings of Oliver Leith, Eva-Maria Houben, Tim Parkinson, Lisa Illean, Alex Paxton, Laurence Osborn and others. Their most recent release is a box set of the complete piano-flute-percussion trios of Morton Feldman.

In 2026 they were Artists in Residence at Kings Place, where their programme of concerts took in celebrations of Morton Feldman and Steve Martland and new work by Beatrice Dillon and Sarah Davachi. Other recent concerts include Steve Reich, Philip Glass and Morton Feldman at Huddersfield Contemporary Music Festival and more Feldman at the Wigmore Hall.

GBSR are hcmf// Fielding Talent artists and the winners of the Royal Philharmonic Society 2025 Young Artist award.
