Released on May 25, 2018, through Sony Music Latin, It is the seventh track on Balvin's fifth studio album Vibras (2018).
It is written by Alejandro Ramírez, Jesús María Nieves, Marco Masis and both performers.
[1][2] Remezcla's Sara Skolnick stated "Brillo is a hypnotizing track anchored by Barcelona-based vocalist Rosalía, whose mission to“revolutionize flamenco” is articulated once again through intuitive hand claps and vocal takes that lend an airy precision in conversation with Balvin's".
[4] After being posted on YouTube for 72 hours, the song was streamed over 170,000 times, becoming a moderate hit for Balvin.
They have sung the track together at The Forum in Inglewood in September 2018 as well as during the Primavera Sound music festival in Barcelona in June 2019, which they both headlined.
