El Filibusterismo (Subversion) is an opera in 3 acts by Felipe Padilla de León with libretto by Anthony Morli.

It is the sequel to Noli me Tangere, another novel by Rizal which was also adapted as an opera by the same composer.

Conductor: Felipe Padilla de León The libretto by Antony Morli was the first prize winner for a libretto contest sponsored by the Musical Promotional Foundation of the Philippines held in 1966.

The music of El Fili had a more intense and contemporary style, compared to de Leon's Noli written about a decade and a half earlier.

Several folk songs and dances were also included in the score like the balitaw, kundiman, and the Kumintang but transformed and given in a more contemporary and modern way.
