IMO the finished product of Led Zeppelin studio recordings is just right for each song. Some are meticulously worked on like Ten Years Gone, and others are just natural as the band laid them down like SIBLY. How Page was able to craft each song and each album is amazing to me. I don't think his contributions to the band or music in general as producer can ever be undervalued. Then there is him and a guitar....... A musical genius IMO.
