Since he was 8 years old, he was pressed by his brothers Jorge and José to learn to play the drums in order to fill the vacant spot they had in their band.

In 1994, when childhood friends Tito Auger and Ricky Laureano returned from the United States, Pedro and his brother Jorge joined them and formed Fiel a la Vega.

The band quickly achieved great success in the island releasing several radio hits and winning several awards.

He also credits Silvio Rodríguez, Rubén Blades, Haciendo Punto en Otro Son, Ismael Rivera and El Gran Combo among his influences in the tropical and Caribbean music genre.

Aside of his work with Fiel a la Vega, Pedro is the drummer of El Asombroso Acto de los Hermanos Arraiza Voladores, and occasionally collaborates with Ricky Laureano and Good Acoustics.
