Formed in 2000, O Duo's first commercial CD was released in January on the Sony/BMG label (8697027202) to critical acclaim - The Daily Telegraph nominating it as CD of the Week (10 February). Owen Gunnell and Oliver Cox were both scholars at the Royal College of Music, graduating in 2003 with First Class Honours. In 2004 they were awarded the first Junior Fellowship to be given to a percussion duo at the RCM and in 2005 they were selected for representation by Young Concert Artists Trust (YCAT).

Since 2000, the Duo has given recitals in music clubs and venues throughout the UK. They have performed concertos with the BBC Philharmonic, London Philharmonic and Philharmonia Orchestras, worked at Abbey Road and Sony studios on television and film scores and broadcast on BBC Radio 3 and BBC TV. In 2003 and 2004 the Duo won 'Best Music Act of the Fringe' at the Edinburgh Festival and in 2006 was shortlisted for the Royal Philharmonic Society's young artist award. Other awards have included the 2005 Royal Over-Seas League Elias Fawcett Outstanding Performance Award, a Tunnell Trust award, the Philip and Dorothy Green Award for Young Concert Artists, the Tillett Trust Young Artist Platform series, and a Martin Musical Fund/Philharmonia Orchestra award.

Over the last year O Duo has given critically acclaimed recitals at Wigmore Hall and Purcell Room, recorded for Channel 4 TV and BBC Radio 2, given concerts in Paris and Madrid and appeared at the Newbury, Cheltenham, Petworth, Brighton and North Aldborough Festivals. This season the Duo return to Wigmore Hall, appear at LSO St Lukes and the Liverpool Philharmonic Hall and give concerts in Switzerland, the Channel Islands and Mexico.

O Duo's repertoire, spans more than 300 years and is a mix of popular classics and accessible contemporary music played on two marimbas, vibraphone and a huge array of percussion. The Duo has performed their own arrangement of Vivaldi's Double Violin Concerto in A minor several times and has started commissioning their own repertoire - concertos and concert pieces by Stephen McNeff, Brian Wiltshire, Ken Johnson and Alan Hoddinott.

Oliver and Owen take a keen interest in education work, working with London Musici, the Philharmonia Orchestra and London Sinfonietta, among others, and giving concerts and workshops in schools and special needs centres around the country.
