Acid Mothers Temple follow up their classic cover of Terry Riley''s In C. This is also the first Acid Mothers Temple record in a long time to feature the voice of Cotton Casino. Double LP is limited to 1000 copies and is pressed on heavy duty virgin vinyl and packaged in a tip-on style jacket. First 200 copies are on color vinyl. Released to coincide with their North American tour.

Beginning with their cover of Terry Riley''s "In C", AMT went on to create "In E" and "In D", as well as their collaboration with Ultrasound on "In G". Now they return to the concept, with four new tracks - "In A", "In Z", "In 0" and "In 8".

As far as music is concerned, a scale could be anything. The names of the scales from A to G are no more than conventions, decided on through human logic. However, beginnings and endings, nothingness and the infinite are not conventions or human creations. Rather they are part of the cosmos and they can be applied to all things that exist. On these pieces they follow their belief in this truth, journeying from beginning to end, from end to beginning, from nothingness to the infinite, and from the infinite to nothingness...

CD version has different art from LP version.
