Ptolemaic Terrascope is a magazine covering old and new music, usually of a psychedelic nature. It has been published irregularly since 1989. Originally published by the Woronzow record label, it covers a wide variety of bands and artists from the 1960s to the present day. Issues typically come with a 7" vinyl record or latterly a CD, and sometimes also special inserts such as artwork, scrap books, and discount coupons. The Terrascope Online website also acts as a focus for the semi-annual Terrastock indie rock festivals which, since 1997, Phil McMullen has curated.
