Weezer confirmed on Double J that they will release The Black Album on May 25th:
“This other album just kind of materialised,” he said. “I had two folders on my Dropbox: one was ‘The Black Album’, and it didn’t get filled as quickly as this other folder, which I temporarily titled ‘New Folder’. That one filled up with ten songs that were definitely different, but not quite as different as The Black Album. So, we put a name on it – Pacific Daydream – and put that out first.”
