[9] Florian and Olivio were born from an Argentinian father, Fabian, and a French mother of Algerian descent,[1] and grew up in the Minimes district of Toulouse, in the Occitanie region.

[10] They both received a solid musical and instrumental training from childhood, Olivio studying trumpet and Florian the drums and piano at the conservatoire de Toulouse.

[12] Their parents had already introduced them to music: their father is a salsa singer[1] and their mother listened to a lot of chanson française when they were children (Jacques Brel, Charles Aznavour and Francis Cabrel in particular).

[15] After obtaining his scientific baccalauréat,[13] Florian spent a year studying at university, in LEA (Applied Foreign Languages),[16] then decided to stop to devote himself entirely to music.

[15] He began writing at the age of six[17] and became involved in musical creation while preparing his economics and social sciences baccalauréat, which he obtained in 2014.

[20] The two brothers grew up, keeping on writing and composing, and started to scour the local scenes as high school students.

[26] The clip, directed by Julien Hosmalin, features comedian Kyan Khojandi and tells the tragic destiny of an Average Joe who ends up losing his temper.

[27] On September 11, 2015, their debut album La Cour des grands is certified gold record and they become the youngest French rappers to receive this award, at the age of 22 and 17.

[30] In March 2015, they put out the music video for the song "Nous aussi", from their album La Cour des grands.

It involves three podcasters: Jhon Rachid, Baptiste Lorber as well as Jérôme Niel, famous for his tutorials broadcast on Canal+'s Grand Journal.

This stop motion clip directed by Nicolas Carnol tells the story of a mother and her aborted child, confronting two opposing yet complementary perspectives.

[33] Bigflo and Oli went live on Facebook on April 30, 2017, and announced the name of their second album, La Vraie Vie, scheduled for release on June 23, 2017.

[40] On the eponymous song "La Vraie Vie", BigFlo took a dig at rapper Orelsan,[41] who turned down a collaboration because of a busy schedule.

[50] At the end of June 2018, the two brothers released a new track in collaboration with French DJ Petit Biscuit, called "Demain".

[51] About a month later, the duo released the associated video clip, mainly consisting of shots of fans dancing during their festival appearances.

The album was released on November 23, 2018[57] and was a huge success, selling more than 44,000 copies in the first week,[58] almost twice as many as its predecessor and was certified gold record after only 10 days,[7] then platinum in less than a month.
