Ramírez was born on May 23, 1992, in Bogotá, Colombia. Raised in Medellín, Colombia.[1] His interest for music production began at the age of 11, when he saw the digital audio workstation called Fruity Loops being used by one of his friends. In 2011, after studying at Berklee College of Music, Boston, he began to work as a record producer for Colombian artists, producing songs like "Amor de Verano" (“summer love”) by Shako, "Cripy Cripy" (a reference to cannabis) by Yandar & Yostin and "En lo Oscuro" (“in the dark”) by J Balvin. During the production of the latter song, Ramírez developed his artistic name; initially, his nickname was ‘Sky’ after being a part of a record-producing duo named ‘Sky High’, but after hearing the sentence "rompiendo el bajo" in the song with J Balvin, he added it to his nickname—transforming it into "Sky Rompiendo el Bajo" or "Sky Rompiendo".[2][3]
During 2012 and 2013, at the age of 20-21, he continued to frequently work with J Balvin, such as on the songs "Yo Te Lo Dije" (“I told you”), "Sola" (“alone”) and "6 AM"; these songs would later be a part of Balvin's first studio album, La Familia, released on October 29, 2013.[4] The record peaked at number one in Colombia and at number 10 on the American Billboard Top Latin Albums chart. The album also received a nomination for the Latin Grammy Award for Best Urban Music Album.[5][6] Sky also worked in the songs "Báilame" (“dance with me”) by Feid and on "Hagan Fila" (“stand in line”) from Yaga & Mackie's sixth album Los Mackieavelikos HD.[3]
Sky achieved commercial and international success with J Balvin as one of the featured songwriters and producers of the song "Ginza" (2015); the song spent twenty-one weeks at number one on the Billboard Hot Latin Songs chart, breaking the record for most weeks spent in that position by a song from a solo act.[7] Since then, Sky has produced all studio albums by J Balvin to date: Energía (2016), Vibras (2018) and Colores (2020), plus also participating in Oasis (2019), the collaborative album by Balvin with Puerto Rican singer Bad Bunny, all the aforementioned albums have peaked at number one in the Billboard Top Latin Albums, with the exception of Colores that peaked at number two.[5]
