Teased in the weeks leading up to its release, London-based girl group FLO share their sophomore effort “Immature.” The song, which details their dealings with love, serves as the second pre-release single ahead of the trio’s forthcoming EP, The Lead, set to release on July 8th.

“Immature” serves as a follow-up to their 90s R&B-influenced track “Cardboard Box,” which upon release, quickly propelled into popularity and earned the group co-signs from SZA, Missy Elliot, and Victoria Monet among others. To date, the music video has amassed 2.7 million views while the song itself accumulated over 8 million global streams. The track is produced by UK-based producer and songwriter MNEK and was later accompanied by an acoustic iteration, following in the footsteps of its original song.

“‘Immature’ is about being strong and confident in yourself and we really don’t have time for someone being immature. It’s ok for you to tell a partner, ‘You’re not giving me what I want and you say you want my body, but you aren’t doing anything about it,'” the group shares. “It’s our more grown up record and the next phase of the story to ‘Cardboard Box.’ We had to dump them in ‘Cardboard Box,’ but this is about why it was necessary.”

FLO is comprised of three members: Jorja Douglas, Renée Downer, and Stella Quaresma. Stella spent the first few years of her life in Mozambique before moving to the UK aged five and met Renée at school in London, where they bonded over their joint love of singing and were familiar with Jorja via social media. Meanwhile, Jorja was born in Germany and grew up in Hertfordshire, and was on her own musical journey. The trio has spent the past two years honing their craft and pulling inspiration from the likes of Mariah Carey, Aaliyah, H.E.R., and SZA among others. Through their first two singles, it’s evident that their hard work is paying off.
