The US grunge outfit will drop their 11th studio album - their first since 2013's 'Lightning Bolt' - on March 27th, and guitarist Mike McCready admits making the album was "emotionally dark and confusing at times".
He said in a statement: "Making this record was a long journey.
"It was emotionally dark and confusing at times, but also an exciting and experimental road map to musical redemption.
"Collaborating with my bandmates on 'Gigaton' ultimately gave me greater love, awareness and knowledge of the need for human connection in these times."
The first single from the record, 'Dance of the Clairvoyants', is to drop in the upcoming weeks.
As well as a new album, the band have also announced a North American tour, which will begin in Toronto on March 18th.
The 'Even Flow' hitmakers will head to the likes of Baltimore, New York, and Nashville, among other cities, before completing the run of shows with two dates in Oakland on April 18th and 19th.
The group are also heading to Europe later this year.
