Callejeros (the Streetwise Ones in Spanish) is an Argentine rock band that became famous when on December 30, 2004, the nightclub República Cromagnon, was set on fire during one of their shows. The fire killed 194 attendees, most of them teenagers. Among the dead spectators were relatives of several band members.

In mid 1995 a group of young people of the Buenos Aires district, Villa Celina got together with the objective to form a rock band. They were first known as Rio Verde and played versions of Chuck Berry, Creedence and The Rolling Stones. In late 1996 the band introduced changes in its lineup. As a result the sound of the band changed completely, reason enough to give a new name to the band baptised Callejeros in 1997.

Between late 1999 and early 2000, there were new changes in the group. In 2001 the band recorded their first album, Sed, (Thirst) which kept in line with classic rock, but this time with the experience of sax player Juan Carbone, ex- musician of Viejas Locas, another popular band in Argentina.

Their second album, Presión (Pressure), came out in 2003 which was launched with a show in Atlanta football stadium in Buenos Aires. The album included fourteen songs, with styles ranging from tangos, ballads, rhythms of candombe rioplatense (black music from Uruguay), Latin rock and standard Rock'n'Roll. This record made their name known in most of the country and a little more in Latin America. The first single, Una Nueva Noche Fría (Another Cold Night), was heavily aired on radio and music TV stations for several months.

After playing in Obras Sanitarias Stadium, also known as the "temple of rock", in 2004, it was anticipated that the band would reach very far, having done so much in such a short amount of time. In only six months, they went from drawing 1,000 people to playing in front of 5,000.

In late 2004 they released their third album, Rocanroles sin destino' (Rock and rollers without a destiny). The album was played live twice: first, in the province of Córdoba, before 10,000 people, and second, in the Excursionistas football stadium in front of almost 15,000 people.

In mid 2006 they released their fourth and long-awaited album Señales (Signs), selling 20,000 copies on it's release day. Its first cut is called 9 de Julio (9th of July, the date of Argentinean Independence) and is already rolling on major radio stations in Argentina.

For this album, the band signed a contract with Pelo Music and had both previous albums (Sed and Presión) rereleased with the company.

The tragic event in República Cromañon marked a turning point in the evolution of the band and they are still playing in spite of the political battle between the City´s mayor, the church and the clubowners.

The band members themselves are defined as a Rock & Roll band and through their diversity comes their own style. Like all bands and all musicians, Callejeros, have a wide variety of musical influences. Influences include Chuck Berry, The Rolling Stones, Creedence, The Beatles, Pink Floyd, León Gieco, Bob Marley, and AC/DC.
