Ultima Esuna's world is a fusion of lush, dreamy productions spanning across dembow, steady drums, alluring percussion, Latin elements, and smooth house sounds. Drawing inspiration from her Latin American heritage, her music seamlessly blends traditional danzón, folklore, and reggaeton. Ultima has already released on her Bandcamp page by December 2020, and she made her debut on the Nervous Horizon Vol. 4 compilation. Furthermore, her song "7 salidas" was premiered on Mixmag, cementing her status as an up-and-coming artist to watch in the music industry. Recently, Ultima collaborated with Vancouver-based band New Age Doom, along with Eli Irreal Veintiuno, to produce a remix for "Life is an Experiment." This track is featured on the album "Lee Scratch" Perry's Guide to the Universe," a project created by New Age Doom in collaboration with the legendary Lee Scratch Perry. Moreover, Ultima is currently involved in an eight-song project that features reworked versions of tracks from the original Magnum Dopus by SPRLUA, featuring SAMITO and Haig V. Her contribution to this project is unique and refreshing, while still maintaining a sense of familiarity.
