I couldn't find any information about an album titled "Signals" by York Höller. York Höller is a German composer known for his works in contemporary classical music, including orchestral pieces and electronic compositions.
One of his notable works is "Fanal," a composition for trumpet and small orchestra, which explores dynamic contrasts and the interplay between soloist and ensemble.
Another significant piece is "Mythos," an electronic work for chamber orchestra, reflecting Höller's interest in integrating electronic elements with traditional instrumentation. (brahms-old.ircam.fr)
Additionally, his opera "The Master and Margarita," based on the novel by Mikhail Bulgakov, showcases his ability to blend narrative and musical innovation.
If you have more details or perhaps a different title, I'd be happy to help further.
