Discussion about artists such as
the Who,
Led Zeppelin,
the Beatles,
Metallica,
System of a Down,
Queen,
George Harrison,
David Bowie, etc.:
They were not prog, but did they do prog albums?
Or did they just make a few prog songs, but not a whole album that could be called prog?
I find this topic attracts many people's attention, and I've seen some very mixed opinions about this.
To back up the first point, I'll give Quadrophenia, Tommy, Houses of the Holy, Abbey Road, Sgt. Pepper's, And Justice for All, System of a Down, Queen, Queen II, A Night at the Opera, All Things Must Pass and Ziggy Stardust as examples to start with. These albums could in one way or another be considered prog; concepts, odd time signatures, polymetres, overall song/album structures that seem too strange for classic rock/metal.
Then again, these elements could be caused entirely by 2-3 songs, and may give a non-prog album a proggy feel/sound, and lead many to believe that an LP is indeed a full-on prog release.
So, which thought do you support? Also, do you have some more examples to back up either of these points?
