Andrés Ciro Martínez

Los Piojos (Spanish: The Lice) is an Argentine rock band. Extremely popular, it became one of the seminal bands of the 1990s Argentine music scene.

Unlike most suburban outfits, however, their style evolved significantly with each successive album, not only developing a unique style for the band but also incorporating elements of murga, candombe, and tango to an electric guitar base. This plus frontman Ciro's songwriting has made them one of the most popular bands in modern Argentine rock, with a strong following across Latin America and Europe, unusual for a band in their subgenre of Argentine rock.
