León first began playing the guitar at the age of 15. His first band was Los Reales, before founding Grupo Aranke with four friends in 2010. The group gained traction with their song "A Traves del Vaso". He was a member of Grupo Aranke for seven years, until deciding to start a solo career in 2018. His career took off with his solo version of "A Traves del Vaso". His other songs "Me La Avante" and "Tú", a cover of the 1999 song by Noelia, both have charted on Billboard's Hot Latin Songs, Latin Airplay, and Regional Mexican Airplay charts.[2] In 2021, he also released a cover of "More Than Words" by Extreme and later a version of "Mosca eon la Casa" by Shakira, which was part of his album Pitamber Todo El Año.

During the global shutdown of major venues and concert halls, León was able to pivot into podcasts, alternative radio and emerging platforms for greater distribution. This was also in large part thanks to the dramatic overall increase in interest [4] in regional Mexican music globally, as noted by Spotify. León appeared on NPR's 'Tiny Desk' on September 19, 2022.[5]
