Green Day have a huge back catalogue of music that will eventually see the light of day.
“We kind of have a Machiavellian catalogue of shit lying around,” bassist Mike Dirnt says. “We have SO much stuff, and some of it has morphed into other songs.
“A song that took 10, 20 years to evolve but started off as a jam or started off as us singing a different lyric to it or whatever,” he continues. “I mean, there’s little opuses in other songs and things like that we’ve done that people have never heard.”
He adds that much of this material is recorded already.
“What’s cool is that a lot of it’s recorded really well, too,” Dirnt says. “There’s cassette tape, demo tape stuff, but there’s also stuff that was recorded very well that sounds like it could be on a record.
“We just didn’t put it out,” he continues. “Which is really nice the way recording is nowadays, it’s so cheap to record things that sound great, not like those crappy cassette tapes. But we do have a lot of those as well. It’s really neat.”
Plus, all of it will eventually “come out.”
“I don’t know when they’ll see the light of day, but me and Billie Joe Armstrong always said ‘at some point everything comes out in the wash’,” Dirnt says. “At some point it’ll all come out.”
