In the simplest terms, the 9 Beet Stretch is Ludwig van Beethoven’s 9th symphony stretched to 24 hours, with no pitch distortions. The original 9 Beet Stretch was done in 2002 at NOTAM (Norwegian Network for Technology, Acoustics, and Music) by Anders Vinjar, Kjetil Matheussen, Leif Inge, and Bjarne Kvinnesland. It was redone at NOTAM in 2004 by Leif Inge and Anders Vinjar, and the concert premiere took place from April 16 to 17, 2004, at Kupfer Ironworks, Madison, Wisconsin, under the production of Jeff Hunt of Table of the Elements.

The 9 Beet Stretch 2.0: Meta Tones is an exploration of the properties of time and acoustics. It is about the design and construction of sound structures built according to the law of chance. It is also about time transformation, musicology, and acoustics. It pushes existing boundaries and genre definitions. It is explained broadly by exploratory sensibilities radically opposed to, and questioning, institutionalized compositional, performing, and aesthetic conventions. It contains elements of indeterminate music, in which the composers can introduce the elements of chance or unpredictability concerning their compositions. Artists approach a hybrid of diverse styles or incorporate unorthodox and unique elements without any rules beyond the taste or inclination of the musician(s) involved. [a]
