Guest Artists
Retired Chicago Symphony Orchestra bass trombonist Edward Kleinhammer has said: “World class players do not just happen…their talents are forged in the dual furnaces of determination and diligence." These “dual furnaces” are more commonly referred to as practice and performance. Improving as a musician requires a great deal of patience and persistence. More importantly, a mental standard of excellence must be present at all times. One of the ways to develop this standard of excellence is by listening to, and working with, great musicians.
OBU has been very fortunate to host many of the industry's leading professionals. We are committed to continuing this tradition. Listed below are upcoming residencies as well as past guests:
