Tectonics 2026 Artist Profile

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 Radio 3).

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 Barbara Monk Feldman to the cracked virtuosity of Alex Paxton and Arne Gieshoff.

Regular performers at Huddersfield Contemporary Music Festival and London's Bold Tendencies, other recent performances include Wigmore Hall, Queen Elizabeth Hall, LSO St Luke's, Royal Opera House, 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, Lisa Illean, Alex Paxton and others. Their most recent release is a box set of the complete piano-flute-percussion trios of Morton Feldman.

In 2026 they are Artists in Residence at Kings Place, where their programme of concerts takes in celebrations of Morton Feldman and Steve Martland and new work by Beatrice Dillon and Sarah Davachi. Other upcoming concerts include Tyshawn Sorey at the Barbican and Charles Ives and Ray Lynch at Bold Tendencies.

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

Oliver Leith’s good day good day bad day bad day

"Oliver Leith’s good day good day bad day bad day is a work to which we feel a deep personal connection. Composed over many months of regular collaboration and experimentation, the piece features several bespoke instruments and techniques developed during that process. It weaves into its musical narrative a series of disarming reflections on performance, relationships, codependency and mental health, within a stage setup intended to mimic our own instrument-strewn flat." - GBSR Duo.
