Judging by the few artists we know that'll be featured, I think they're going down the Indie/Pop route. Which is super mainstream now, however Linkin Park's never done it before for an entire album.
I'd love an album to be like chill indie pop/alternative R&B. As long as their risks and we don't get the pop of Living Things. I know the band will be able to make something work.
Chester has already mentioned in their Facebook live stream that the vocals are totally different from what they done before. so maybe that could be meant with "different"
So the hype continues today. I'm hoping we don't have to wait until tomorrow for the next video/letter.
