Perpetuum Jazzile is a Slovenian choir that performs jazz and popular music. It was founded as Gaudeamus Chamber Choir in 1983 by Marko Tiran. In 2001, Tiran passed the art directorship of the choir to Tomaž Kozlevčar, the renowned music producer, arranger and vocalist, who was followed by Peder Karlsson ten years later. A group of people with a lot of enthusiasm, it gives me goosebumps when I listen to it.See for more.
