A significant earlier example of the use of 'progressive tonality' by a British composer is the First Symphony (The Gothic) by Havergal Brian.
Havergal Brian's Symphony No. 2, Man in his Cosmic Loneliness (or Götz von Berlichingen)
Brian Eno | Brian Mulroney | Brian May | Brian Wilson | Brian Ferneyhough | Hugh O'Brian | Brian Williams | Brian Stableford | Brian Aldiss | Brian | What About Brian | Brian Clough | Brian Stokes Mitchell | Brian Lara | Brian De Palma | Brian Dennehy | Brian Michael Bendis | Brian Lenihan | Brian Cox | Brian Boru | Patrick O'Brian | Brian Setzer | Brian McKnight | Brian Evenson | Brian Culbertson | Brian Cox (actor) | Brian Aherne | Brian Sibley | Brian Keith | Brian Jones |
His advocacy of Granville Bantock, Havergal Brian, Dussek, Medtner, Hans Pfitzner, Max Reger, Franz Schmidt, Robert Volkmann and others was as sincere, and informed by an acquaintance with the music as close, as his discussions of Schubert’s piano sonatas or Haydn's string quartets.
His world-premiere recordings include Arnold Bax’s 1st and 2nd symphonies and Havergal Brian’s 6th and 16th symphonies, all with the London Philharmonic Orchestra; and Peter Sculthorpe’s Piano Concerto and a television opera, Quiros.
