This band from Springfield started out in a very peculiar way around April of 2003, doing jam sessions of Andean Rock Music. After months of rehearsals and a line up change the went into a different musical direction. The band members began to experiment with their musical backgrounds and influences which was a mix of hard rock, metal and grunge, and that led to the birth of Filtro. A sound of heavy and hard guitars with metal, punk and hard rock rythms led by strong lyrics talking about social issues and personal experiences.

Filtro has had a few line up changes on the bass but now Julio, Javier, Luis and Ed keep writing original material that is influenced by the different musical backgrounds of each member that ranges from Led Zeppelin, Black Sabbath, G N' R, Nirvana to R.A.T.M., Audioslave, Chevelle, Korn, Molotov, Soda Stereo, Metallica and more.

Filtro is now a familiar name in the latin rock scene of the Washington DC Area having performed in may venues of Virginia, Maryland and DC and is also part of the annual DC Latin Rock Festival.

Filtro is classified by their fans as having a "LOUD, STRONG and UNIQUE" sound.
