In November 1967 Laszlo Heltay was invited to form a choir for the Brighton Festival which was planning a performance of Walton's Belshazzar's Feast to be conducted by Sir William Walton on 11th May, 1968. The performance was a huge success and launched Brighton Festival Chorus as an important part of the music scene in Britain and, under Laszlo's directorship, one of the most successful choirs in the country.
Laszlo Heltay remained Brighton Festival Chorus' Music Director for the following 27 years during which time the Chorus formed long and close associations with a number of leading orchestras and conductors including the Royal Philharmonic Orchestra, Andre Previn, Vladimir Ashkenazy and Lord Menuhin who was the Chorus' President until his death. Highlights of these years include a memorable Bach B Minor Mass with Karl Richter, Kodaly's Psalmus Hungaricus with Istvan Kertesz for Decca and many concerts and recordings with Antal Dorati.
Laszlo lived in Barcelona for several years where he was closely involved with the Madrid Radio Choir as well as continuing a busy schedule of conducting and master classes for young choral conductors in Europe and the USA. More recently he has returned to live in Budapest.
Records and Recording described Laszlo Heltay as "One of the finest and most inspiring choral trainers in the world....Through his efforts the whole British choral tradition has been given a new look and a new set of standards to aim for."
