Chester is aware that he made the comment before with MTM, but here is another comment from Chester about the heaviness of the album.
At the same time, working with Mike [shinoda], the guy's so prolific and he has such good vision and he's been listening to a lot of really great punk and metal music that I have a feeling -- I've made the mistake of saying this before, when we were making Minutes to Midnight, I was doing this interview and at the time we were writing really, really heavy music and I said, "It's going to be the heaviest record we've ever made!" And then it came out and it was just not heavy; it was, like, the opposite.

This is what Austin Carlile from Of Mice & Men recently said in an interview. We know he is friend with Mike but this is some cool info.
You guys are keeping hard rock alive...
Oli Sykes: We're trying to!
Austin Carlile: We're trying to get the torch passed. I was recently with Mike Shinoda, and we were talking about that. I want the torch. I want rock music to come back. The bands back in the day were the biggest. Those numbers of records sold don't exist anymore, but I feel like people still love the music just the same. I think they're just waiting for artists to come out with albums like that. That's why everybody likes Bring Me The Horizon's record so much because it does that. It's new, and it's good. That's what we hope they do with our new album too.

Also, in this interview with Mike, about 2 minutes in, he also talks about how they said MTM would be heavy and it ended up not being heavy. He gives no other info about the sound. But why would he bring up that exact thing if the new music didn't remind him of it being heavy? Lol.
Kevin & Bean interview with STP from 2013.
''I was in the studio yesterday with the boys from Linkin Park and we happen to be writing some pretty mellow music that I was screaming my brains out to until 10 o' clock last night''
