A performance-centred archive, largely comprising files of music that relate to concerts given by the Early Music Consort of London (founded and directed by David Munrow) and to their audio recordings. The archive also contains Munrow's scores and arrangements for television and film productions, as well as some radio scripts. Material relating to the 1976 publication Instruments of the Middle Ages and Renaissance, and some correspondence, is also included.

The catalogue for this collection can be found in The National Archives.

Percussion instruments donated by the late Christopher Hogwood CBE Hon RAM and used by the Consort are catalogued in the Museum collections database.
