I've listened to Echoes and One of These Days in the past and I thought they were great. And is Animals really just that? I guess it can wait. Any other album I should buy soon?
I'd say that if you really like Echoes and One Of These Days, you should definitely get Meddle.
Although most of Animals only really has three songs, they are all lengthy and are conceptually tied together.
The Animals tracklisting is:
1) Pigs On The Wing (Part I) - just under 90 seconds long
2) Dogs - 17 minutes long, takes up nearly the whole of side one of the vinyl
3) Pigs (3 Different Ones) - another long song, but shorter than Dogs at 10 minutes
4) Sheep - similar length to the previous song
5) Pigs On The Wing (Part I) - again, just under 90 seconds long
In terms of other Pink Floyd albums, if you get Meddle and Animals on top of the 'big three' then you've got all of the major Waters and Gilmour albums. the most obvious album to listen to next would probably be The Piper At The Gates Of Dawn, although as the only true Syd Barrett Pink Floyd album it's quite a bit different from the 1970s albums - if you have a strong preference for the later sound over their psychedelic era, and if you like Meddle, then maybe go for Atom Heart Mother instead (IMO that's the first album where the classic progressive Pink Floyd sound is heard).
Thanks for posting that song, Aktivator - I'd not heard that one before, and I rather like the sound of it. I am alone I thinking it sounds a bit like a Joe Walsh song?
