The actor-musician spoke to Reuters about Tenacious D's new album Rize of the Fenix, which he predicted will not be given a proper critical appraisal by the mainstream press.
"I do love [Jack White's] Blunderbuss, I love the Foo [Fighters], I love Tom Waits, his new record is incredible... and Goyte... but our album is better than all of those, and because we're clowns, we don't get that kind of love," Black commented.
Black went on to joke about what Tenacious D's legacy will ultimately be.
"In a hundred years' time, no-one will remember Gotye or the rest, but the shining beacon of The D - they're going to start religions after us," he teased.
The band complained about the state of rock music last week, with Gass joking that the genre is suffering from "pneumonia" rather than being dead.
Tenacious D kick off a summer tour in Santa Barbara, CA on May 23.
