I agree they are underrated. The first 3 albums were very creative. Then they became more mainstream.
Give 'Ambrosia' another listen
Ambrosia. It's been years since I put them on, and I'm blown away. There are a couple of their albums that rival Sgt Pepper in creativity. Very under rated band IMO. The albums, 'Somewhere I've never traveled' and their self titled one are my favs.
Imagine Yes, Chicago, the Beatles, and Klaatu mixed together, with a great vocalist.
