Supplementary music for "Lines Over Lines" project

I had to cut things short for time during the last presentation, but I had really wanted to play you some music as well. The following musicians represent an auditory response to some of the very same ideas that visual artists were considering: modularity, repetition, reductivism, de-centered focus, heightened awareness.  The results are very hypnotic. All three musicians were deeply influenced by Eastern classical music, particularly Indian, which incorporates long, harmonic drones.

LaMonte Young, Theatre of Eternal Music, "The Tortoise, His Dreams and Journeys." First performed 1964, but continues to be performed in different formats to the present. Note for lovers of hidden history: collaborating with LaMonte Young in many early projects was John Cale, later to be an integral part of The Velvet Undergound. The tortoise picture is silly, sorry.

Terry Riley, "A Rainbow in Curved Air," 1969. Note the grid right there on the cover. The entire album is fantastic, but I would recommend starting to listen at about 18:50. Riley was an early adopter of experimental electronic sampling and looping technologies.

Philip Glass, "Two Pages," 1969. Glass may be the most familiar of the three through soundtracks for Einstein on the Beach, Koyaanisqatsi, Thin Blue Line, and a number of contemporary film scores, among other things.
