Tagumpay De Leon (also known as "Pi" De Leon) is the son of the late Philippine composer and national artist, Felipe Padilla de Leon. In 1991 he helped to form the Rondalla Club of Los Angeles (RCLA), along with the late Nitoy Gonzales, former Rondalla maestro of the famed Bayanihan Dance Troupe from the Philippines, and Leonilo "Boy" Angos, also a former member of Bayanihan, son of Nitoy Gonzales.
Rondalla, the traditional string ensemble of the Philippines, often provides the music for Philippine folk dances and is prominent in community celebrations like fiestas, weddings, and other civic and social events serving the Filipino community.
Since its inception, RCLA has remained active in various Filipino social and civic functions and is recognized as one of the leading rondallas in southern California. It has been a familiar fixture in Pilipino Cultural Nights (PCN) held in different universities, colleges and high schools.
Mr. De Leon teaches the Philippine Music Ensemble in the Department of Ethnomusicology.
