Index initially was released as 12" vinyl in 1996, under the project name Helical Scan. It was long out of print, and this month it is back on vinyl, with a different mix on the B-side, and a new, rougher, louder and more detailed mastering. If you have no turntable, never mind, here it comes via the magic internet.
