This week we have the new album from one of rock's biggest bands, a two-hour slab from a long-running noise band, a psychedelic debut, and a new metal (not nü-metal) supergroup.

Black Keys - Turn Blue
The Black Keys return from their longest ever gap between albums—a whole three years—with a new record. (iTunes required)




Down - Down IV Part II
Convoluted Coheed and Cambria-ish album title aside, this new EP from New Orleans sludge supergroup Down (ex-Pantera, Corrosion of Conformity, Eyehategod) is the band's first without long time guitarist Kirk Windstein, who left to focus on his band, Crowbar. (stream via Noisey)




Swans - To Be Kind
Long-running noise rock band Swans are back with a new two-disc, two-hour set. (Read the AllMusic review)




Golden Grass - Golden Grass
Brooklyn-based psychedelic band Golden Grass is releasing its debut later in the week. (stream via The Obelisk)




Killer Be Killed - Killer Be Killed
Metal supergroup Killer Be Killed is Greg Puciato (Dillinger Escape Plan), Max Cavalera (Soulfly, ex-Sepultura), Troy Sanders (Mastodon) and Dave Elitch (ex-Mars Volta). (stream via Metal Sucks)
