9 Beet Stretch, by Scandinavian sound artist Leif Inge, is a piece of idea-based sound art made of Beethoven's Ninth Symphony. The source recording, a Naxos recording conducted by Béla Drahos with the Nicolaus Esterházy Sinfonia and Chorus (Naxos 8.553478), was stretched digitally to a duration of 24 hours with no distortion or pitch shifting. The work is presented as a 24-hour-long sound installation/electroacoustic concert.
