For 2020, I’m going to focus on the “essential classics” of the 70s. To get a bit more variety than just a whole bunch of Black Sabbath and David Bowie, I am going to abide by the rule of “only 1 album from this decade per artist.” This January, for the year 1970, I am getting (1) Black Sabbath - Paranoid (2) Led Zeppelin - III (3) Van Morrison - Moondance.
