Well this was their first "pop" album and it's really good. First rate. Their better albums are "The Yes Album," "Fragile," "Close to the Edge," "Relayer," and many many more through the 2000s. Lots of good tunes, way more than the Beatles who I love by the way. . .
If you're new to Yes, stick to the short songs. Their "half an album songs" are kind of hard to take if your're not used to this kind of music. At least that's what my wife tells me. They're in the same league as Jethro Tull, Early Genesis, ELP. . . Greats if you ask me.
