Notwithstanding the fact that I never heard
Skinny Fists or the second Moodies' album mentioned, I think none of the albums mentioned is pretentious. For instance, I love Yes'
Tales From Topographic Oceans because Yes didn't think that the idea was too far out. They just did what they wanted to do, and thirty + years later the album still
shines, after the release of so many muzak through the years by other artists. I hate it when the so-called serious music press is condescending in its attitude towards the 'pretentious' progressive rock.
Still, I must say I had to smile a bit, some time ago when I listened to an old Earth & Fire album, called Song Of The Marching Children, and looked at the subtitles of the title track:
Song of the marching children (18:20)
...a) Theme of the marching children - 2:20
...b) Opening the seal - 1:10
...c) Childhood - 3:10
...d) Affliction - 1:30
...e) Damnation - 2:53
...f) Purification - 4:17
...g) The march - 3:02
Well, I wouldn't call that pretentious either, it's just a charming portrait of an era. So: I wouldn't know a pretentious album. And Journey, Pictures, Tales and The Lamb are just brilliant.
