With the demo coming together by the end of the 84-minute video, one fan then asks Mike to do the same thing inspired by the sound of the band's fourth album, 2010's A Thousand Suns.
"The thing that's pretty magical about A Thousand Suns…" Mike ponders. "As soon as we hit our third record, Minutes To Midnight, everything after that I think there was a lot less blueprint going on. Things sounded like us when they sounded like us because it was us, but one thing about A Thousand Suns was that it was a lot of happy accidents and things we stumbled on to in a great way. Like, you'd just be feeding a keyboard through a pedal, and that through another tape echo, and then all of a sudden a weird sound would come out and we just made sure we were recording, and turned that into a part of a song. It was a lot of that."
He adds that he's up for doing "weird sound experiments" in his next livestream, though, saying, "That would be fun. I guess the magic there too isn't just finding the weird accidental sound; it's hearing it and recognising, 'Oh, that's a cool sound, I like that sound,' and then turning it into a song. That's kinda the hardest part."
Yep, we'd totally be down for watching Mike experiment like that.
