They released their first album, Jardín Frenético, independently in 1996. A copy of the album would later reach to Gustavo Santaolalla, who upon listening signed the band to Surco and became their producer. However, both Méndez and bassist Patricio Pizarro decided to leave the group at this point. Following the incorporation of two new members, the band would then re-record most of their original album for a self-titled major label debut in 1999.
Following two highly successful albums, international tours and a live DVD, composer and multi-instrumentist Edu Schmidt left the band in 2006 to pursue a solo carrer.
The band moved to Popart Discos producing their following works by themselves, and Diego Velázquez became an official member in 2009 to perform most of the instruments that Schmidt used to play with them.
Árbol has been in hiatus since late 2010.
