The tracks "Stones", "Fingerprints", "Trocosi", "Levity", "I Want it to be Over" and "In the Winter of '64" were recorded for a WDR radio production by Alexander Schuhmacher in January 1997.

I was supposed to create pieces spontaneously, using my choices from a long list of sampled fragments which I heard only after arriving in the studio.

[2] In the MIT Press journal, Leonardo, Stefaan van Ryssen wrote that the recording process of Prints give the tracks an "immediacy and urgency".

[3] He described "Stones" as a waltz, "limping as if hit in the leg by a bullet", and "I Want it to be Over" as a "miniature drama" with improvisation that is "top class".

Van Ryssen said the pieces are deceptively simple, but repeated listening reveals that the relationship between the samples and instruments is "subtle and never obvious", and they leave one "[in] awe at what a master improviser can do in real time".
