As of my last update in October 2023, there is no widely recognized artist by the name of Volker Hornback in the music industry. It is possible that he is an emerging artist or a figure in a niche genre that has not gained significant mainstream attention. If you have specific details or context about Volker Hornback, such as the genre they work in or notable works, I could provide more tailored information or help clarify any confusion. If you are interested in another artist or a different topic related to music history, feel free to ask!
