J Balvin & Rosalia

José Álvaro Osorio Balvin (born May 7, 1985), known professionally as J Balvin, is a Colombian reggaeton singer. Balvin was born in Medellín, Colombia. At age 17, he moved to the United States. He moved to Oklahoma and New York to learn English and was influenced by the music he heard there. He then returned to Medellín and gained popularity performing at clubs in the city.
His breakthrough came in 2014 with the single "6 AM" featuring Puerto Rican singer Farruko which peaked at number 2 on the Billboard Hot Latin Songs chart. The song, along with the single "Ay Vamos", bolstered sales of his album La Familia (2014). In 2016, he released Energia, which included the hit singles "Ginza", "Bobo", "Safari", and "Sigo Extranandote". In June 2017, J Balvin released the single "Mi Gente" featuring Willy William.
On 1 August 2017, "Mi Gente" topped the Global Top 50 on Spotify, and later reached one billion views on YouTube. The song, and its remix featuring American artist Beyoncé, helped J Balvin achieve international fame. In January 2018, he released the hit single "Machika" featuring Jeon and Anitta.
Though his music is primarily reggaeton, J Balvin has experimented with a variety of musical genres in his work, including electronica, house music, trap, and R&B. His original musical inspirations were rock groups such as Metallica and Nirvana. He has collaborated with artists such as Pharrell Williams, Major Lazer, and Sean Paul. Despite working with many English-speaking artists, J Balvin continues to sing almost exclusively in Spanish, and hopes to introduce Spanish-language music to a global audience. He is also noted for his eclectic and colorful fashion sense.

Rosalía Vila was born in the year 1993 in Sant Esteve Sesrovires, Spain. She is a Spanish flamenco singer.

Her career includes the duo with Juan Gómez Chicuelo at the 2013 Panama International Film Festival and at the Grec Festival in Barcelona for the contemporary dance work De Carmen.
