Los Reyes, originally known as Los Reyes del Cuarteto, is an Argentine musical group formed in 2002 in Junín. Initially performing for senior audiences, they transitioned to a broader repertoire, focusing on cuarteto—a vibrant genre blending cumbia, fox-trot, pasodoble, and tango. Led by accordionist Julio "Grillo" Núñez, the band has released multiple albums, including "Volumen I" (2005) and "La octava maravilla" (2014). Their dynamic performances and dedication to Argentine musical traditions have earned them a dedicated following.
