quarter mile groove
Today and Tomorrow points to Quarter Mile Groove, a conceptual art piece by Daniel Eatock.
The recording translates the length of its vinyl groove into audio allowing listeners to experience the 1/4 mile length of the spiral as the record is played.
I like that Eatock included the vinyl residue of the initial master cutting of the record as part of the piece. When unraveled it would (obviously) be a quarter-mile long.
