Your top 15 progressive music albums IN the '70s?

I know...right.   I don't know how my brother ended up with Festival.  It was the only 70s Santana I remember listening to...circa 1978. I liked it.  I still like it.  Probably whistful little girl memories. 

 Since then I prefer earlier Santana.  I didn't dig early 70s Santana till the late 80s. Call me a late bloomer. 

Rush- Hemispheres 

ELO- Eldorado

King Crimson- Lark's Tongues in Aspic

Jethro Tull- Heavy Horses

Pink Floyd- Wish You Were Here

Genesis- Trick of the Tail

Again and again, PLEASE, respect the OP.

all but Zappa although I do have some of his later albums. I mostly agree with the list but the inclusion of Time and a Word (I would put in Caravan's release for that year instead as per PA) and lack of Gentle Giant would get a few hot under the collar. I would also put in Pawn Hearts instead of Tarkus for 1971. No recognition of the RPI scene either but PFM best albums came out in 1972 and that is a tough year to crack.

That's still four more albums than I own in the list.

How many of these 33 classic prog albums do YOU own?

I can also tell that it's a good question how familiar I was with the term "progressive" in the '70s, even I think that I heard it at least, as one of my class mates was very much into Genesis and VdGG, and if I remember well, King Crimson, and he payed much attention to different cultural trends. 

I had a period when I was almost only into instrumental music, so that was definitely my most important way to distinguish between different kinds of music (if disregarding distancing myself much from the much Pop-influenced, not least The Beatles), so albums like The Birds of Fire, Where Have I Known You Before, Sea Sun, Ommadawn, The Snow Goose, Clearlight Symphony, Stratosfear and Oxygene were to me almost the same kind of music. "Almost" because I also thought of the latter three ones as electronic music.
