That's the artwork for the "Attack Music" single, thanks to the Angular website...
...wait, what's this? According to the same site, the format for "Attack Music" is download and...nope, just download.
It upsets me that - outside of the initial single announcement - every thing about this single is turning out all sorts of wrong.
[Maybe they forgot to list it and there will be a 10" as well, but I'm not holding my breath.]
