"It has always been my dream to mix Steely Dan with No Means No," Dave Grohl says of the eclectic sound of the sixth Foo Fighters album, "Echoes, Silence, Patience and Grace," due this week via RCA. "If anybody is going to do it, I'd love to be that guy."

Indeed, the 12-song set may throw some fans for a loop, as tracks like "Let It Die" and "Erase/Replace" make drastic stylistic shifts in a matter of seconds. "There's four-piece rock band sh*t, but then there are songs where the middle sections turn into this mass orchestrated swarm and ridiculous time signatures," Grohl says of the new material.

Among the rockers sure to sizzle in arenas this fall are opener/first single "The Pretender" ("It's a stomping Foo Fighters uptempo song, with a little bit of Chuck Berry in it") and "Cheer Up Boys, Your Makeup Is Running."

At the other end of the spectrum, "The Ballad of the Beaconsfield Miners" finds Grohl and guest guitarist Kaki King flexing their fingerpicking. "This song is almost banjo-picking style with hammer-ons and pull-offs," Grohl says. "I showed it to her once and she shredded it 10 times better than I've ever played it."

Throughout the album, there are numerous left-field musical references to "Band on the Run"-era Paul McCartney, the Eagles and other softer-rocking relics of the '70s. "There will be times when you hear it and you'll go, 'Wait a second. Was that Bread?' It's a trip," Grohl says.
