Calabro has over 100 works to his credit including music for traditional and non-traditional chamber combinations as well as for both large and small orchestral ensembles most notably in America.
Calabro believed in writing music for those he knew best and had the distinction of hearing virtually everything he wrote performed during his lifetime.
Louis Calabro founded the Sage City Symphony in 1972, an ambitious community orchestra in southwestern Vermont which is still active and continues to commission new works.
Calabro believed strongly in encouraging and promoting contemporary music, at a time when few American orchestras (professional or amateur) were performing premieres.
Composers whose work was premiered under his baton include Marta Ptaszynska and Vivian Fine.
