In 1982, La Monte Young and Marian Zazeela used two tambouras to create a document that will go down in history. They are also a strong tribute to their Guru = Pandit Pran Nath. The thick drones of the tambouras create a moiré-like effect, and the meditative state itself is brought out in this highly pure meditative work. There are many sources of minimal and drone music, but I've never heard anything that brings about such a spiritual transformation. It's like something that's been flowing for thousands of years, and it's in a perfect state that can't be cut down or added to. The 44-page booklet is included.
