SLÄPSTICK was founded in 1997 (originally under the name 'Wereldband'). Ro Krauss, Willem van Baarsen, Rogier Bosman and Sanne van Delft met during their conservatory studies, and decided to start a band. The core of the SLÄPSTICK was born, and is still in tact to this day. Jon Bittman joined the group in

A budding friendship, combined with the communal quest for new and strange musical instruments and a shared need for laughter led to fresh and interesting ideas. Although they happily plundered music from the existing wells of many genres, they began writing more and more of their own compositions and song texts. From 1997 onwards SLÄPSTICK performed at various music venues and festivals, while at the same time developing ludicrous theatrical scenes to accompany their tunes. In 2005 they made the inevitable leap to the theatre stage. The guys deftly switched between trumpets, violins and musical saws the way a juggler might play catch with a bowling ball, a flaming torch, and, well... a musical saw. A SLÄPSTICK show is a carousel of instruments, always ready to spin off its axis and into a humorous situation, a musical delight, or a touching scene. 

Next to developing their own shows, SLÄPSTICK often works with various other well known artists from the Dutch, and international worlds of music, dance, and theatre. Among others, they've worked and performed with Brigitte Kaandorp, Ellen ten Damme, Karel de Rooij, Martin van Waardenberg , Titus Tiel Groenestege and Stanley Burleson. 

In August 2017 SLÄPSTICK performed at the Edinburgh Fringe Festival, where their show 'Släpstick' was met with 5 star reviews, Scottish TV appearances, and full halls. Press and public from all over the world left the show delighted and hankering for more. It's a good thing then, that SLÄPSTICK is going on the brink of taking "Släpstick" worldwide in 2018. Keep an eye on the "Agenda" above to see when Slapstick will be coming to your country!
