Martinu, born 1890, is a casualty of the 20th century's music wars, an original mind who refused to follow either of the dominant ideologies, nationalist or atonalist. Prolific beyond belief, with more than 400 works to his credit, he is all too easily dismissed as a central European windbag without a defining hit. His last opera, The Greek Passion, has been staged twice at Covent Garden but otherwise you can go from one decade to the next without hearing more than 10 minutes of Martinu at a stretch - and that, all too likely, in the insomniac hours of classical radio.
