How can a drummer not appreciate Led Zeppelin? John Bonham was the greatest of all time(not to be confused with the greatest living, which would be Neal Peart).
Bu I'm glad to see you mention YES, in your favorite rock bands. They are actually my all time "favorite" rock band, which is a different list, than the "greatest" bands that I listed(in fact I can't stand the Stones, but I have them as number 5, on greatest of all time). YES, who began in 1969, are finally being inducted into the Rock and Roll Hall of Fame, this year. Is there any other band, that makes music like YES?
