Gentle Giant

Here is a very interesting band I was actually turned onto by my brother and one of his friends.  English prog rock band Gentle Giant was active between 1970 and 1980 and in that decade, they came up with some very unique music.  It is prog rock.  But, it also has medieval themes and the lyrics are quite compelling.  Not just the lyrics, but also, the phrasing.  An example of this can be found in a video of a concert from 1978.
