The bands performing in the Entreezaal, the stage by the main entrance, have the important task of stimulating and enthusing visitors as soon as they enter. These bands have to arouse people, stimulating their appetite for more swing, more jazz, more blues. A Hammond organ, baritone sax, guitar and drums. That's what we find in the quartet Swingmatism, promising juicy shuffles, powerful boogaloos and ballads from the jukebox era. The group is made up of four young musicians who have been making a name for themself since graduating from the conservatory.
