Mellow and STiLGoNE joined forces in late 2023 to release B.O.L.O., a 7-track debut that reflects the DIY spirit of their collaboration. The project began in the basement of drummer Keelan Evins, where the initial recordings were laid down. From there, production moved to a garage studio set up by Mellow at the home of lead vocalist and guitarist Symon Palmer, where Mellow was also living at the time. The result is a raw and intimate collection shaped by the spaces it was made in. Released on December 22, 2023, B.O.L.O. features original cover art by Jacob Garvin.
