I am sure it will be on all digital retailers due to Universal partnering with the label that the album is on.
Yes, I already see the media reporting that these are new Chester vocals. The band actually has not done a good job in setting that straight, in my opinion. It makes me wonder if they are shying away from saying there are no new Chester vocals because they want to drive attention to it from folks thinking this is an all new project with new CB on it. I really have no idea, that is just a hypothesis. There's really no information on this project out there at all anyway, besides that a release is coming. No time frame, no confirmed guests, no tracks, etc.
