It's the 20th anniversary of their 2002 album, but the cover is very poignant. The 2002 cover was a bright, vibrant and in bloom flower. 20 years later, they put out the 20th anniversary edition and it's just a dead rotting flower stem covered in thorns. Sort of a memento mori. Reminds me of how much life and the world have changed since 2002, so I think it works really well for the album.
