No. Fish is not trying to sound like Peter Gabriel. He just sounds like him. When still in Marillion critics said Marillion sounds like Genesis. Peter Gabriel said, "No, they are better than Genesis." I have seen Fish and Peter Gabriel live. I love them both.
I haven't commented on this band before. I think that this is a good song. I like Marillion, but it seems to me that he's trying to try to sound a little to much like Peter Gabriel. Watch was able to pull this off by doing it with artistic intent. I just don't think that it sells here if you are a Peter Gabriel fan.
The accessable sound of prog music; Ok so it's a simple melody and benign lyrics but hey, the guy can hold a tune, produce a great instrumental break, and it keeps me coming back for more; keep on that curve Fish!
