On September 14th, I had the chance to present a lalelu drums performance together with the percussionist duo BeatBop on their concert 'Hands On!' in Friedenskapelle Kaiserslautern (Germany). They had a diverse program featuring many different percussion instruments played directly with the hands (no drumsticks) and together we prepared the piece 'Rapper's delight' with body percussion and lalelu drums adding a marimba bass line. I am very grateful for this opportunity and I really enjoyed the preparation and the concert together with Jonas and Timo!

Here is a video of the rehearsal. At first I introduce lalelu drums by playing individual marimaba notes. Then, I play the bass line using a combination of individual notes and predefined patterns. Jonas and Timo join in, clapping and slowly marching to the stage. They have a solo after which I join in again.

Note that the first and second part (before and after the solo) feature a different tempo, which is possible because the predefined patterns are played at the tempo defined by the preceding individual notes. Also, the tempo is continuously updated from the player's movements. I will make a blog post soon, giving more details about these features.
