But some have criticized the launch, including The Winery Dogs drummer Mike Portnoy, who slammed Floyd, saying releasing a new record was "disrespectful" to former mainman Roger Waters.

But Akerfeldt insists people should "shut up and enjoy it" as the record still features Floyd's core members. He tells I Heart Guitar: "I think people should be happy that Pink Floyd are doing a new record - they should just shut up and enjoy it. If they like it or not, David Gilmour has been at the head of the band since the mid-80s and if the music features Rick Wright who passed away, why wouldn't you want to be able to listen to it?
