The file includes press cuttings, 1952-1964, relating to the Cardiff Music Club, opera and ballet productions in Cardiff, and to the formation of a national orchestra for Wales.

The title of the file suggests the existence of other files, now mislaid.

The series consists of correspondence, programme notes and proofs, posters, contracts, invoices, programmes, newspaper cuttings, order forms, accounts, mailing lists, itineraries, duty sheets and press releases and papers relating to the organisation and to the staging of the concerts around Wales, 1975-[1993].
