The quartet released its first full-length album, Astro, in 2011.
Despite being entirely in Spanish, the album received attention from American music critics.
Jasmine Garsd called Astro one of her favorite albums, referring to it as "infectiously cheery, light-hearted and danceable."
She described them as musical cognates with American bands such as MGMT, Animal Collective, and Passion Pit.

In 2013, Astro performed at the Lollapalooza Music Festival and their song "Panda" was featured on the soundtrack of FIFA 13.
