Bert Appermont composed the music for the first ever open-air musical, the Seed of Satan, which was shown for the first time in August 2002, in Kruibeke, Belgium. This gigantic spectacle which evolves around witchcraft at the beginning of the 17th century, attracted more than 10,000 spectators in just a few weeks. Bert Appermont subsequently arranged a suite of the highlights from the musical which he has called Saga Candida.
