[Eddie Vedder] added he had been mulling an album title that was a play on Soundgarden's Superunknown: "I was thinking of the word 'un-owned' -- not owned by anybody," he said. "The sky is un-owned. The moon is un-owned. We're un-owned. We want to remain un-owned. The title was Superun-owned."
Said to be aggressive, the grunge band’s newest work is supposed to be the band’s hardest effort and is tentatively set to release in April 2006.
