What do The Rolling Stones, Muddy Waters, Crosby Stills & Nash, Sly and the Family Stone, Earth Wind & Fire, Black Sabbath, Little Richard, and Roxy Music all have in common? You're probably thinking "they're in the Rock & Roll Hall of Fame, obviously!" And while that is a brilliant thought and undisputed answer, it's not the correct answer. The proper response is "they're all clues to find this cache." Good luck!
