Dio Day

Rock fans, metalheads, and lovers of legendary riffs! Dio Day returns on July 19, now rocking harder than ever at Cortland County Music Park.

This annual celebration honors the life, legacy, and thunderous voice of Ronnie James Dio, one of heavy metal’s most iconic frontmen and a Cortland County native. Expect a day packed with live music, tributes, and a community of fans who know every lyric, every solo, and every set of devil horns.

Whether you grew up blasting Holy Diver or you’re discovering Dio’s legacy for the first time, Dio Day is a can’t-miss summer event celebrating rock history where it all began.
