Actually, the first couple of years of the 80s, 1980 and 81 were really more of a transitional period. It was the 70s winding down and the sunrise was just beginning for the new decade. While 1982, '83, '84, '85, '86, '87, '88, and '89 all had different musical and stylistic trends and various happenings to make those years identifiable, the first couple of years of the 80s didn't have such things so therefore in hindsight 1980 and '81 (especially '81) seem to be the period of the 80s that was just..'there'. 1981 seems to have become sort of like the 'lost' year of the decade. About the only thing that really happened between 1980 and 82 was that, on August 1, 1981, MTV premiered. It would make the 80s what it was and changed how music is promoted forever...but it wouldn't be until 1983 when MTV really took over the culture of the 80s.(Click here for my small mini-thesis on MTV in the 80s)
The musical marketplace in the first two years of the 80s was pretty much 'anything goes'. Between 1980 and 1982 it was nothing to hear Hall and Oates, Alabama, and Van Halen on ONE radio station. This period was a very fascinating time in music of the 80s. Before MTV really kicked into gear, we were left to wing it...and that's why I'm most fascinated by the 1980-82 period of the 80s because it seems so...obscure.
I remember, amid all the syrupy Air Supply and Kenny Rogers songs cluttering up the airwaves, how exciting it was to hear this wierd sounding keyboard fade-in like a flying saucer landing and then hearing Billy Squire and his band suddenly explode into that killer riff of "In The Dark" from his "Don't Say No" album. After hearing those songs, you knew the 80s was going to be one dynamic decade.
