Letter from a Band Director
“The clinic made a significant impression... I cannot get them to stop practicing improvisation, nor do I want to! The musicians were outstanding, demonstrated a high standard of performance for the students, and offered a sincere educational experience towards the students. I would wish that performances/clinics of this kind [were] offered throughout the school year."
Greg Garcia
Band Director at J.L. Matthey Middle School
