Marvin J. Davis, performing as Qool DJ Marv, operates as a music specialist and atmosphere curator with deep roots in the 1990s New York City and Philadelphia underground scenes. He maintains long-standing residencies at Dumbo House and Soho House Manhattan, where he utilizes a mix of jazz, house, and soul to define cinematic soundscapes for luxury hospitality environments. His work extends into digital broadcasting through the Buttamilk-FM brand, specifically hosting the newly launched radio series, The Departure Lounge. This project transitions his live performance expertise into a global format, offering curated global moods and high-fidelity audio transitions. Marv has historically collaborated with cultural icons like Erykah Badu and Jill Scott, and he recently expanded his archival reach with the Sounds Of The Season collection, which documents multi-tempo jazz and holiday textures. His expertise in environmental music makes him a frequent contributor to hospitality panels on the psychological impact of audio on community spaces.
