YES THE SNOW GOOSE
I am so happy to see Camel's The Snow Goose on that list. While it's about as metal as a wooden spoon full of custard, it's an awesome album, and I think I can sort of see how it is important to metal, even if that importance is not necessrily the most expected. I'm not sure he means "first" genesis album, though. I think he may have forgotten FGTR exists, otherwise it's a very interesting list.
