Jerry Blavat, the Philadelphia radio DJ and performer best known to his fans as the "Geator with the Heater," will be posthumously honored with a musical tribute during the Italian Market Festival on Ninth Street next month. The annual block party at the nation's oldest outdoor market will take place from 11 a.m. to 6 p.m. on Saturday, May 20 and Sunday, May 21.

South Philadelphia natives and visitors alike can meander through the Italian Market and experience long-held traditions like the Procession of Saints, greased pole climbing contest and the John Marzano Halfball Tournament. Blavat died from an autoimmune neuromuscular disease on Jan. 20, leaving arts institutions throughout the region devastated as performers and radio personalities remembered his seven-decade career.
