Four performers each bring three books for the other three performers to read from.
During performance, they all read to themselves, reading certain words, sentences, or passages out loud during one-minute time brackets as given by the score.
The time logic intersects clock time with elements of musical improvisation (since often, the words or phrases can be placed very freely within the time spans given), but also with the completely different temporality of reading a text which might be new to you, bringing in rhythms of its own.
