One of the benefits of having our trumpet prof., Paul Morton, as head of the UL Concerts committee is always having a great brass group come to campus, and the masterclasses that usually come along with it.
2 1/2 years ago we had the St. Louis Brass come in, whose newly appointed hornist was the esteemed Thomas Bacon. My students Jim and Alex each had what amounted to a private lesson with Thom, with me observing. One of the big things we (and especially Alex) took away was the directive to "never let them hear your WATER!!!"
Well, I reminded Thom of that just now on Facebook, and his response appears above!
