Lancelot Beresford Bryan Fairfax (8 February 1925 – 11 January 2014) was an Australian conductor based in the United Kingdom, who was known for his championing of little known or neglected works. He was strongly associated with the works of Havergal Brian, and he conducted the world premiere of Brian's Symphony No. 1, Gothic in 1961. Brian's Symphony No. 18 was written especially for Fairfax and the semi-professional he founded. His UK premieres include major works by Gustav Mahler, Dmitri Shostakovich, Carl Nielsen, Sergei Rachmaninoff, Franz Schmidt and Percy Grainger. His conducting style has been likened to that of Sir Adrian Boult and Vernon Handley.
