Los Aslándticos, a Spanish world music group, originated from Córdoba. The band began as friends who gathered behind an old cement factory to perform their original compositions, blending social commentary with everyday experiences. Their debut album, El Mundo Está Fatal de los Nervios, was released in 2005 under Disparate Records and later reissued by Sony BMG. In 2009, Mario Díaz left the band, leading to Bueno Rodríguez taking over vocals and songwriting duties. Their second album, Mi primer día, was released in 2009 under Maldito Records. The band achieved chart success with singles like "Sin Duda" and "Hoy ya Está Bien," both reaching Number 1 on Canal Fiesta's Top 50 list. Subsequent albums include Lo Bueno (2012), Vivos! (2015), Aquí y Ahora (2017).
