Boy are you clever, you sure showed them.
Did you copy and paste that from Blender?
WRONG. They're still an incredibly influencial band. And calling them insignificant is about the most retarded thing I've ever heard, even the most avid Yes haters would call bullsh*t on that.
They are considered by many to be the defining band of their genre, which was by no means insignificant when it was one of the the dominate genres of rock music in the early 70s, as brief as that was, progressive rock is not insignificant and that is something even prog haters should accept, progressive rock is f*cking huge and people underestimate how popular it is today, and how much of an influence it's had on modern music both directly and indirectly.
