The most melodius flute's solo in the Prog. Rock

[Andyyyy]

For me it's Firth of Fifth, already mentioned. I do like Steve Hackett's brother, John. Aside from Voyage of the Acolyte, there were some great live moments with the two of them. Chicago had some good flute here and there too, especially on Chicago VII.

Andy! There another too, very melodius that is in the nice work of K. Crimson, "In the Court of the Crimson King"!
John Hackett is a good flute player too!
Embrace brother!!
