The Lost Music Network (LMN) published 26 issues (A-Z) of OP Magazine. I discovered it at issue P at the Collegetown record shop in Ithaca, NY on the way home from classes one day. My subscription began with issue R. I ordered a back copy of the A issue, but never completed the set.
My preferred offshoot after OP completed its series was Sound Choice. It lasted for 17 issues.
OPtion was the other offshoot after OP completed its series. It lasted quite a bit longer, although I gave up on it after XX issues.
