In May 2007, the Jay Sharp Memorial Concert Organ of 103 digital ranks was dedicated in a performance of Saint-Saëns' Organ Symphony #3. Stevens is among a handful of high schools anywhere possessing a large concert organ; a three-manual, 84-stop instrument in the Milo Winter Fine Arts Auditorium. The orchestra regularly fills All State more than any other school. Its success stems from longtime director Bill Evans who started with a group of five players building it over 40 years to a full orchestra with 120 members.
