Oh wow, good for you, never got to meet him but he is one of my favorite players, what a great musician. Looks like he is a great teacher as well.
For whatever reason I thought David Luidold was teaching bass trombone there. He and I subbed together in the Deutsches Symphonieorchester Berlin many years ago. Top player as well.
He is not only a fantastic teacher, also a great human being
Yeah he was teaching in Graz, Mr. Ströcker is teaching in Oberschützen(a part of university of music and performing arts Graz). David was actually one of my first teachers
