It looks like Nickelback will be making an announcement this Friday (August 14th). The band tweeted what appears to be an album or single cover with the heading “Friday 8/14.” Nickelback's last album was 2017s Feed the Machine, so the band could very well be announcing a new album.
Nickelback had planned to celebrate the 15th anniversary of All the Right Reasons on tour this summer but it was canceled due to the coronavirus pandemic. They will, however, release a 15th anniversary deluxe edition of the album on October 2nd.
Earlier this year, guitarist Ryan Peake teased that a documentary on the band has been completed.
