When publications label you as "the best singer in the world," it's probably a wise decision to avoid bells and whistles when performing. Tuelo does just that in her performance for Positive Vibes Only, stripping down the instrumentation of "Saint Margaret" to create what feels like a private performance of the intimate track.

Assisted by only her guitar, the former background singer turned solo act delivers a must-hear vocal performance. Listen to the South African native's full, breathtaking rendition below.

"Saint Margaret" was originally the standout title track from Tuelo's 2017 EP. Five years later, "Saint Margaret" is reenvisioned as a part of the singer/songwriter's debut album, The Life of Margaret Cornelius.

There is heavy South African influence on The Life of Margaret Cornelius, and in Tuelo's genre-bending sound as a whole. Infectious drums, powerfully stacked vocals and guitars that rip through the song are all common practice for the uncommon experience that is listening to Tuelo.
