He started playing with Juantxu Olano in a band called Ke and they recorded a four songs demo tape.

The following year, Fito gave an interview to the press and he confirmed that he left Platero y Tú, and consequently the group disbanded.

Antón also formed another band called Inconscientes that year and released a studio album in 2007 under his own label, Muxik.
