The choir that turned Toto's Africa into one of the most-watched music clips on YouTube - using nothing but raw vocal magic - is coming to Belgrade. Perpetuum Jazzile, the Slovenian a cappella ensemble, perform on December 7 at the Blue Hall of Sava Centar. For anyone who has seen that performance online at least once, this is the chance to hear the same sound live - not a single instrument, only voices.

The group was founded in 1984 as the Gaudeamus Chamber Choir, and today numbers around 45 singers. International fame arrived in 2009 with their rendition of Africa, in which the choir simulates thunder and rain with palms and feet before the melody kicks in - a trick borrowed from South African choirs. The clip racked up over 50 million views and made them the most-watched large vocal ensemble in the world.

The story went beyond internet fame. The cover's success reached Toto themselves, who loved the version so much they invited the Slovenians to perform alongside them at a concert in Udine. What Perpetuum Jazzile does on stage is turn the human voice into an entire orchestra - rhythm section, brass and soloists, all of it produced with the mouth alone.

The concert at Sava Centar starts at 8 p.m., and tickets are available via tickets.rs. For an evening where the instruments are surplus and the voice is everything, this is one of the more interesting events the region has to offer this winter.
