When Matthias Kessler (b. 1997), Luca Staffelbach (b. 1996), and Fabian Ziegler (b. 1995) play the works of French composers, they use up to two marimbas, three vibraphones, and two glockenspiels, sometimes more, sometimes less. The three musicians, all of whom hail from Switzerland and Austria, have dedicated five years of development work to their debut CD. The ensemble's common denominator is a great desire to explore the infinite potential of percussion instruments.

Their bachelor's degree courses at the University of the Arts in Zurich paved the way for the three young musicians to explore the entire spectrum of instrumental possibilities from the outset, and their mutual interest in their subject matter extended far beyond the huge variety of drums and other percussion instruments they had to hand, right up to the so-called "mallet instruments".
