Approaching the original score from a contemporary perspective, this new interpretation of Williams Mix contains a close analysis of the relationship between early tape music and current digital production, including video, allowing for original parameters of the score to be realized within the context of recent audio-visual technologies. The video component of Williams Mix Extended, created by Lillevan, will focus on the permutation and transformation of John Cage´s tape notation into visual art. Williams Mix Extended has an duration of 32 minutes whereas the original is 4 minutes and 15 seconds long. The difference between the two durations is generated by the transposition of the score´s specifications from tape to digital audio software. To complete Williams Mix Extended a library of approximately 2000 different sounds is used, all recorded by Dafeldecker and Valerio Tricoli.
