Since Richard Watkins is primarily known for his classical music career as a horn player and does not have a background in electronic or dance music, creating a biography that focuses on electronic/dance music contributions for him would not be accurate or relevant. Watkins' distinguished career in classical music, including his tenure as Principal Horn of the Philharmonia Orchestra and his work as a concerto soloist and chamber musician, does not intersect with the electronic or dance music genres. Therefore, it wouldn't be appropriate to rewrite his biography for a DJ/electronic music tracklisting application under the provided guidelines.
