Rutger Zuydervelt (aka Machinefabriek) invited 41 drummer/percussionists including Tony Buck, Vasco Trilla, Tim Barnes, Greg Stuart, Cyril Bondi, &c. to take part in a project by recording a few short fills or phrases, which Zuydervelt used as "Lego Bricks" to build a series of short rhythmical collages, the results being 24 diverse and fascinating compositions.
