3. The Black Keys - 'Turn Blue'
The Black Keys have been crafting music with Brian "Danger Mouse" Burton for years, but on Turn Blue he essentially became a third member of the group, producing and co-writing much of the material in addition to playing keyboards. Some of the blues rock tracks will remind listeners of the earliest Black Keys records, while others are almost danceable. "At this point," said Dan Auerbach, "there are absolutely no rules."
