My Morning Jacket  is celebrating the 20th anniversary of their acclaimed 2005 album, Z, with today’s premiere of the previously unreleased “The Devil’s Peanut Butter,” which is available everywhere now. The echo-laden romp heralds a special new expanded edition of Z, arriving through ATO Records on October 3.

“I remember the melody of ‘The Devil’s Peanut Butter’ popping into my head as I strolled across the harbor bridge in Sydney, Australia, near the Opera House,” says My Morning Jacket singer, guitarist and songwriter Jim James, “staring down at the eerie grinning entrance face to Luna Park.”

The artist adds: “I worked on it some more while staying at Bondi Beach, walking amongst the graveyards and lawn bowling clubs that sit up high on the cliffs overlooking the beautiful coves of the Pacific Ocean. I have no idea why we called it ‘The Devil’s Peanut Butter,’ but our producer, John Leckie, absolutely did not like the title and we laughed about it quite a bit. For some reason, it just didn’t seem to fit on Z, but we all loved it, then forgot about it for 20 YEARS, and now here it is back to life again! We hope you enjoy!”
