about us
a wonderful, adventuresome, sensitive pair of musicians
- Kate Molleson, BBC R3
GBSR Duo - George Barton (percussion) and Siwan Rhys (piano) - combines two of the UK's finest young contemporary chamber instrumentalists. The duo has built its reputation on a combination of exceptional interpretations of the existing piano-percussion repertoire, committed performances of ambitious new commissions, and inventive collaborations.
Known for their fearless, intense and boundary-crossing 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 composers like Morton Feldman, Eva-Maria Houben and Barbara Monk Feldman to the experimental and cross-genre work of Oliver Leith and CHAINES.
​
With an emphasis on commissioning and repertoire-building complemented by the respect and trust of composers, GBSR's recent world premieres include works from Eva-Maria Houben, CHAINES, Lawrence Dunn, Cassie Kinoshi, Alex Tay, Linda Catlin Smith, Julius Aglinskas, Tim Parkinson and many others.
Their freewheeling collaborations range from team-ups with leading musicians like the Heath Quartet, EXAUDI, 12 Ensemble, Sean Shibe, and the LA Philharmonic, to inventive cross-disciplinary pairings with artists like Angharad Davies, Dejan Mrdja and Cameron Graham.
​
GBSR were the winners of the Royal Philharmonic Society 2025 Young Artist award, where the judges commended them for a “commitment to new music that’s thrilling in its fearlessness…their programmes and collaborations fizz with style, energy and invention”.
​
Recent performances include the duo's US debut performing Oliver Leith at Walt Disney Hall with the LA Philharmonic and Thomas Adès, and their Lithuanian debut playing new works by Lawrence Dunn and Julius Aglinskas in Vilnius and Kaunas. Other recent premieres include Alex Tay, Cassie Kinoshi and Linda Catlin Smith at the Wigmore Hall; Joe Duddell and Luke Lewis at Three Choirs Festival; and the multimedia theatrical electronica of CHAINES at Spitalfields Music Festival.
Forthcoming concerts see the duo at the Aix-en-Provence festival in an innovative reduction of Britten's Billy Budd for four on-stage instrumentalists by Oliver Leith and Ted Huffman; at the legendary Darmstädter Ferienkurse, where they will appear as resident ensemble performing groundbreaking multimedia and spatial audio works; and at London's Southbank Centre in multiple concerts.

​
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 extraordinary new works in premiere recordings of Oliver Leith, Eva-Maria Houben, Lisa Illean, Alex Paxton and others. Their recording of Stockhausen's KONTAKTE on all that dust was hailed as “a landmark performance” by Tom Service on BBC Radio 3; it was made album of the week in The Guardian and named “the best spatial audio purchase I’ve made this year” by Seth Colter Walls in The New York Times in 2023.
