"Of all the people that could have been chosen for the task of creating a dictionary for the modern lowbrass player, Yeo is perhaps the most appropriate to undertake such a project. As a performer - having served as bass trombonist in the Boston Symphony Orchestra for nearly 30 years - and pedagogue - having held faculty positions at the New England Conservatory of Music, Boston University, the Peabody Institute of Johns Hopkins University, Arizona State University, and Wheaton College - his name is recognized and respected in the world of modern low brass. Additionally, he is a well-known champion for and practitioner of historical lowbrass instruments, which, with his practiced eye and knowledge of the history of these instruments, serves the dictionary and its readers well. ""is interest and yearning for knowledge are clearly the driving forces behind the volume's success, making it an invaluable resource for any modern low-brass practitioners, students and teachers, amateurs and professionals."
