The new Queens Of The Stone Age album is their strangest yet, according to frontman Josh Homme.
Homme said it's been a struggle to record the new album, which was originally promised by the end of 2011, but the result is ultimately "deeper, richer and stranger" than previous releases.
He was speaking to BBC Radio 1 (via Antiquiet) when their Masterpieces series featured QOTSA's 2002 classic "Songs For The Deaf", which recently appeared as one of our Top 10 Concept Albums.
Homme said the new album "sounds like you're running in a dream the whole time," by the end sounds like "a spoonful of sugar." With every other record, he would "pull every trick I know to wrap hooks in strangeness," but this time, "the final trick I have is 'no trick at all.'" Whatever that means.
Special guests will include Dave Grohl on drums, and Trent Reznor has been helping out with some electronic elements. Former bassist Nick Oliveri has also returned to provide vocals, though it's not clear how far his involvement will go.
The BBC Radio 1 'Masterpieces' session is available to UK listeners for one week, and offers some fascinating insights into the recording of their classic "Songs For The Deaf" album.
Could the new QOTSA record be a return to form for the band and become another rock classic? Let us know what you think in the comments.
