If this was in English I would describe this particular song as mainstream indie-pop, pop-rock or power-pop with a late 90s or early 2000s feel. Compare the following:
Third Eye Blind - Semi Charmed Life (1997)
Fountains of Wayne - Hey Julie (2003)
Weezer - Island in the Sun (2001)
Phantom Planet - California (2002)
Their Wikipedia page describes them as having a strong blues influence, which isn't evident in this song, but is in some of the other tracks I heard. It's a more pop version of the blues then you usually hear in America --the closest thing in English is probably early "British invasion" music like Eric Clapton or the Yardbirds.
You might try searching power-pop, indie pop, or pop-blues on Spanish language search engines or resources for Spanish language bands with this sound.
