Animals, has almost the entire time I've been a Pink Floyd fan (since around 1991 or 1992), I have always seen as my favorite. And it was released January 23rd, so if the older version of me had heard it in 1977, it likely would been on top all year and not been topped. Although I love A Farewell to Kings and up to that point, I probably would consider that Rush's best album (of course not for long!, lol), but I doubt then and of course can rate it at the level of Animals.
Ironic as I'm finally finishing this extensive list, Roger Waters is playing in town tonight. And I've never actually seen him live (I heard him outside once or twice, lol), and he actually is playing half of Animals. (Pigs and Dogs) But I'm not going unfortunately per I saw Bent Knee on Monday and plan to see Bubblemath on Saturday. Plus I should get to sleep early tonight or my lack of sleep this week may catchup with me.
But hopefully another time (hopefully Roger isn't done, but at his age, who knows. If he needs money? I suppose it may not be). and if he were to play the whole Animals, I would not miss it. He's done Dark Side and The Wall to death, and the casual fans of course look to those 2 and then Wish You Were Here well before Animals for some reason. Likely Classic Rock radio and the length of the songs having to do with that.
Dave Kilminster does a lot of David Gilmour's parts, which is fine, but I have seen Animals live twice before (local MN band Soap did it), and Kilminster with Steven Wilson, so the loss doesn't feel so much. There's also plenty of videos on YouTube from the tour.
Anyway, beyond Animals though, 1977 was the year Punk was becoming big, but despite that., there was plenty of prog and jazz-rock. Even just Classic Rock, Power Pop and Psych stuff, many of which I of course listed below in the calendar, but know only from reputation or just ratings that I want to check out.
