Following closure in 1959, the church stood derelict and roofless for some 40 years, but since 2003 has been a music centre operated by the London Symphony Orchestra and known as LSO St Luke's. It is the home of the LSO's community and music education programme, LSO Discovery. The main body of the building seats up to 372 and is used by the LSO for rehearsals, and by a wide variety of musicians for performances and recording. Additional rooms in the crypt provide practice facilities for professional musicians, students and community groups.
