As the name implies, the BUMfest International Percussion Festival is a rather specialised music festival. Taking place in Žalec and established in 2007, its quite successful and regularly sold out musical programme presents all sorts of percussion and drumming projects that often feature elements of theatre, dance, humour and sound experimentation. Beside evening concerts, the festival also comprises music workshops and matinee performances for schoolchildren,
Led by Dejan Tamše, of the SToP Slovene Percussion Project, the festival takes place at the Dom II. slovenskega tabora Žalec. An additional venue is the Savinov likovni salon, where post-festival exhibitions sometimes take place.
The festival has hosted artists from Taiwan, Brazil, the United States, Mexico and numerous European countries. Some of the guests in recent years have been Funky Currywurst Brothers (AT, DK), Percussive (BE), Odaiko (ES), Groovetrotters (DE, AT), Quatuor Beat (FR), Sudar Percussion (HR), Percossa (NL) and The Strokes (HU).
Furthermore, the festival is sometimes amongst the initiators for projects like "Faces and Places", which featured the SToP Slovene Percussion Project, the Studio Percussion Graz (AT) and guest musicians who had come to Europe as refugees or migrants.
