I've discovered this composer today, and he's really interesting!
His name is Hans Huber, and he was a Swiss composer.
He has composed eight symphonies, some tone poems, and the only two surving piano concertos (1 & 3) by him (all of which have been recorded by Sterling).
Some chamber music has also been released and 24 Preludes and Fugues, Op. 100, of which I haven't found recordings.
His first symphony is perhaps somewhat similar to Brahms, but there's a foreshadowing of Sibelius in some of the orchestral textures.
There are a number of threads on Huber here already. Please follow these links and post there, if relevant:
