It's My Chemical Romance's new CD.
The music is excellent, of course. Planetary (GO), SING, and Save Yourself I'll Hold Them Back are my personal favorites, although honestly they're all good.
The real selling point for me, though, was the world of the Killjoys. MCR has released music videos for Na Na Na and SING (both brilliant) and I love how they fit together to form a storyline. SING actually made me tear up a little when I watched it.
