Shego released their first single "adiós" in 2020 and have been regularly putting out punk-esque bangers since. Their most recent being "la kiero a morir" which is moody and engaging, playing with dynamics through clever use of instrumentation and obscured backing vocals.
The nearly constant use of vocal harmony is something that I've begun to associate quite heavily with the Spanish quartet. The first song of theirs that I discovered was "meperd0nas?" which is slightly less polished than "la kiero a morir" but just as charming and was definitely enough to get me hooked on the band and I think that this song might just hook you in too.
