It's for the re-release of Be Human. They're releasing it with 4 or 5 new tracks around tour time in October. This has been known for weeks. It's not a secret at all lol.
If it's not that then they're finally recording the score for the movie "In God We Trust" that they're making with Horsie In The Hedge (www.hithmedia.com
). If that's the case then I imagine they'll be re-releasing Be Human with songs that were recorded during the album recording sessions.
It's safe to say that this is most likely just them recording the 4/5 new songs for the Be Human re-release though.
