Anyone listen to Camel? I've just finished listening to their discography up to Stationary Traveler. Very underrated prog rock band, highly recommended especially if you like instrumental prog. They have some vocals but it wasn't long before they realized that instrumental music was their strong suit. Their first four albums, Camel, Mirage, Snow Goose, Moonmadness, should be essential listening for any prog fans. Breathless and Rain Dances are also good.
Unlike many other prog bands, they didn't lose their charm in the 80s. They began to sound slightly more commercial and they definitely adapted to the more contemporary production styles. The only album that I felt they lost their way on was The Single Factor.
