In June 2003, they started recording in a studio and in September of that year they won the Joven Promesa (Young Promise) contest organized by El Masnou.

Helena Miquel "las flores azules", who made the chorus for the song, joined the band indefinitely.

In November 2005, they released their first album, vs. El Monstruo de las Ramblas on the Music Bus label.

By the end of 2006, they recorded several songs for Bigas Luna's Yo soy la Juani soundtrack.

The music of Facto delafé y las flores azules is halfway between indie pop and hip hop, with melodies and structures more characteristic of rock, soul or electronic music.
