What is the epic song of a group?


I will start. I vote for Stairway to Heaven for Zep. Its grand with a great finish. I will throw in Salisbury by Uriah Heap. Ok lets see some posts of what you think is a groups masterpiece.

Epic... in terms of production, sound quality, songs, etc... I'd vote for two Supertramp albums:  Crime of the Century of course, but also the less appreciated (post-Hodgson) Brother Where You Bound.  Several tracks are a musical journey, and reference quality sound production.  I've heard 3 different CD pressings of "Brother" over the years, and my first edition CD from 1985 is still the most dynamic.  Get it if you can!
