In 2014, Oliver releases his first album Twenty Deux, recorded for more than a year in many studios around the world. The album has allowed him to perform in many countries, such as Brazil, the USA, Italy, Spain, Israel, Belgium and France.
In 2015, the single “מחר” (mach’ar) comes out. The song is an Hebrew adaptation of his successful French song Demain.
In 2017, Oliver releases "Got to be there" featuring 3 deejays.
The song gets in the Belgian UltraTop charts thanks to its wide broadcast on radio, live performances in major festivals, and reposts by several international deejays (Wolfpack, Tiësto, and Steve Aoki).
After many shows in Brazil between 2013 and 2018, Oliver records "Fortaleza", his first ever song in Portuguese, released in January 2019.
