I had never heard of the Swiss composer Caspar Diethelm before coming across this new 3-disc set of his symphonies and other orchestral works from Guild while browsing MusicWeb International. Reviewer Marc Rochester was very enthusiastic about this release, nominating it for Recording of the Month. He mentions Sibelius, Hindemith, Nielsen, Martinu, and Bartok as passing influences on Diethelm's style, but asserts that he has an individual style. It sounds quite tantalizing to say the least!
