Sean Gregory works as a composer, performer and creative producer throughout the UK and overseas. He leads collaborative arts projects for all ages and abilities in association with many British and international orchestras, opera companies, theatres, galleries and arts/education organisations. His commissions range from chamber works to large-scale collaborations in the community and have included performances at the Barbican, the South Bank Centre, Bath and City of London International Festivals, as well as in Mexico City, Brisbane, Gothenburg, Madrid, Manilla and Acco (Israel).

Sean is Head of Professional Development at the Guildhall School of Music and Drama in London and Artistic Director of Guildhall CONNECT. A wide range of projects provide opportunities for participants to develop individual creativity, to extend forms of performance practice both within and outside the Guildhall School and to foster a shared understanding between people from different cultural backgrounds.

Sean is also responsible for a postgraduate programme in Artistic Leadership, established by the Guildhall School to enable arts and education practitioners to develop further the fundamental skills for sustained personal, artistic and professional development in the areas of creativity, flexible performance and communication. Connections are being established worldwide with individuals and organisations, in New Zealand, Australia, Tanzania, The Gambia, Brazil, Mexico, Scandinavia, Spain, Israel and The Philippines.

Central to Sean's work is the facilitation and development of new ensembles (from three-piece to 30-piece) with line-ups that include vocals, strings, wind, bass, rhythm sections, non-western instruments and technology. He has recently established One Functional Distortion, an ensemble dedicated to exploring new musical-visual landscapes, by drawing on local and global influences through collaborative composition, improvisation and performance.
