The sound comes from Medley Apache (En Vivo) by Mexican singer Carin Leon, with the existing description identifying it simply as Kumbia, a spelling variant of cumbia. Cumbia is a Latin dance genre known for its steady rhythm and festive feel, and Leon is known for performing regional Mexican music live. Online, the long live medley has been reduced to this sub second snippet and shared on soundboards under the stylised name KUMvia, where its brevity makes it useful as a reusable musical accent rather than a standalone track.
