It's really difficult for me to be objective because there was so much cultural baggage surrounding Pink Floyd when I was growing up...I find it hard to listen to any of the post-DSOTM albums without associating them with the ignorant yahoos who would cruise around my high school parking lot smoking cigarettes and proudly flaunting their disdain for intellect while cranking Animals or Wish You Were Here on their Alpine car stereos...
I know, I know, that's my problem.
Likewise, it's difficult for me to be objective about how good DSOTM really is because I discovered it at a point in my life & my musical development when I was primed to be blown away by that sort of large-scale concept album. Plus clearly it's affected millions of other listeners, and it's hard to separate that cultural impact from the actual music.
So again, I'm probably not being very objective. Duh, what else is new?
But fwiw I think everything they did prior to DSOTM was interesting & got increasingly so, up until DSOTM which was the absolute zenith of their career...and then everything subsequent sounds to me like they just kept trying to write DSOTM2: The Sequel.
Though I did kinda dig the album that Tony Levin played on.
