4x3

4x3 was a Mexican rock band from Monterrey that formed in the early 2000s. They released their self-titled debut album in 2006, which included the song "Toxico." That track became their most recognizable work, though its explicit content about toxic relationships led to some radio bans in certain countries.

The band's lineup featured Rogelio Bañuelos on lead vocals and guitar, Rafael Hernández on bass, and Miguel Luna on drums. They put out a few more albums after their debut, including "Hablando en Serio" in 2008 and "Crédeme" in 2011. Other songs in their catalog include "Demonio," "Perfecta Para Mí," and "Adelante Sin Rendirte."

4x3 announced their dissolution in 2016, but they've reunited occasionally since then for special concerts. Their music, particularly "Toxico," still gets played and remembered by fans.
