Brace yourself for a surprising evening, because Radio Guga is back! In the theater show Ondersteboven (Upside down), the rules of a concert are turned upside down, because the audience decides. The choices are made à la minute and you get something new served up. Suddenly changing genres, singing voice, or even musician: it's all possible. You can just choose ‘Poesje Stoei’ by Urbanus, in a tango version, sung as a duet between William Boeva and Willy Naessens. Every evening is unique. The band led by Guga Baul naturally remains what it has always been: the dream version of a cover band, with a top singer who also knows how to imitate the voice perfectly. Add a portion of Guga humor to that and your evening can't go wrong.
