He joined the faculty of the Curtis Institute of Music in January 1994. He has also held faculty positions at Rowan University and guest faculty status at Indiana University of Pennsylvania and the Manhattan School of Music. Mr. Liuzzi just completed 10 years as music director of the Philadelphia All City High School Orchestra, and is founding conductor of the Curtis Institute's 20-21 New Music Ensemble.

Mr. Liuzzi's early orchestral experience included the Flint Symphony, the Michigan Opera Theater Orchestra, and the Colorado Philharmonic.

Red Winzer

Together with his widow, Kumi Murashima, we mourn the loss of our good friend and colleague Red Winzer, a member of the MLSO and its board for many decades. Artist/Bassist Clif Anderson, his section mate for many years, memorialized him in this painting. Below is Clif’s tribute to Red, addressed to Kumi:

Red was a warrior and a champion to me. His fortitude to stand up for what was right demanded that I pay attention. I've had so many memorable moments with Red and they all stand out: being in the bass section with him, having a beer with him after rehearsal, dinning out with you and him, visiting with the two of you at your home and condominium in Hawaii, and as you will see in the photos that will follow shortly, our relationship was personal.

Red was instrumental in getting me back to the Delaware County Symphony which I had ties with going back over three decades when we were in residence at the Delaware County Community College. When the funds were not available to give me a stipend for performing, Red used his own funds to pay my remuneration. He thought it important to have a strong bass section(at least four) and his respect for my playing and participation over the years was not to be ignored.

She was especially beloved by the members of her section and she will be deeply missed by the entire orchestra.

Jennifer's family has requested that donations be made in Jeni‘s name to Main Line Symphony Orchestra.
