Behind Bronquio hides Santiago Gonzalo, a young punk musician who began his career in hardcore scene. His work as a producer ended up pushing him into the world of laptops and sound cards, while always maintaining a dissenting attitude. Activist of the rhythm, his last incarnation as Bronquio seems in the trap scene what The Prodigy has been in the world of drum n bass: a 180 degree turn.

In 2018, Bronquio released its first video and digital single Galgo, a whiplash synth-punk where Santi had the vocal collaboration of Pablo Peña (Fiera, Pony Bravo). Selected #INESTalent by the Innovation Network of European Showcases festival network, Bronquio has already played at festivals such as Monkey
Week, Low, Tomavistas, Vida Festival, Primavera Trompetera, Nocturama...
Galgo was followed during the following months with a barrage of successive digital singles that complete the particular proposal of this urban music artist: Niño (a tribute to flamenco legends Lole and Manuel), Bodega Ultra / Semifucsia (double single where trap singer 41V1L participates) and Tu Portal (where it has had the collaboration of the new kings of the underground cumbia psycho Esteban & Manuel). In 2019, time for Estás Chill, Manifestación, Altar and Contigo, Contigo, Contigo, the smash hit feat. Carlangas (Novedades Carminha). His last step has been 'Vol.1', a four-piece EP via Altafonte Spain (June 2020).

Bronquio is also known for his work a a mixer (Rocío Márquez, Camellos, FAVX), producer (Kiko Veneno, ‘Sombrero roto’; Natalia Lacunza) and musical arranger.
