Six Feet Under definitely have a theme with all of their albums and Graveyard Classics 3 is no exception. All they asked was that it be an angel's skeleton and the rest was up to me. I really tried to do something fresh for them, but also keep it stylistically within the realm of their other covers, specifically the 1st Graveyard Classics album. Overall, it was a quick but positive experience and I've got nothing but respect for them as they were a complete joy to work with.
