Green Day are rumoured to have finished their new album, though the rumours are based completely on the fact that the band no longer have reserved car parking spaces at the Ocean Way studio they were working at.
Presumably that could mean that they have gone somewhere else to work on the LP. But yes, I suppose it could mean that the band have finished altogether.
Anyway, here's what a posting at fan site Green Day Authority says about it: "Back in November we learned that the band was recording at the same studio where they recorded 'American Idiot', Ocean Way Recording in Hollywood, California - the same place where they recorded previous albums as well".
"Someone decided to go check it out, and found the guys' parking spaces reserved, pretty much confirming the band was definitely there recording. A few days ago another visit to the studio showed the parking spaces were no longer reserved, leaving us to assume that recording is done; though, with no official word from the band, we can't really make any promises".
The band are also rumoured to be planning their live comeback at this year's Coachella, but they haven't reserved any parking spaces at the festival site, so it's possibly too early to tell.
