 In time, the bulk of Lyrita's catalogue became orchestral and symphonic works, including otherwise-neglected composers at that time, including William Alwyn, Malcolm Arnold, Arnold Bax, Havergal Brian, Frank Bridge, Arnold Cooke, Gerald Finzi, John Foulds, George Lloyd, Edmund Rubbra, Humphrey Searle and Cyril Rootham.Many Lyrita LPs became regarded as demonstration discs, suitable for showcasing the sonic qualities of high-end hi-fi equipment.Nearly all of Lyrita's recordings were produced by Decca Records and pressed by either Decca or Nimbus Records.
