Gorillaz resurface quickly with ‘The Now Now,’ a very mixed new album

Is there really another Gorillaz album out? We were still trying to digest last year’s overstuffed “Humanz.” And shouldn’t we be wary of a new release so close to that 26-song project?

After spending time with “The Now Now” (Warner Bros.), the answer is yes — yes, indeed.

The 11-track collection includes some of Gorillaz’s funkiest riffs — but also some of the weakest tunes in the band’s catalog.

“The Now Now” has basically two speeds — either up-tempo, synth-washed EDM or maudlin, half-thought-out ballads.

There’s nothing of the band’s previously signature approach — dizzying levels of collaboration with cool guests. Other than George Benson, Jamie Principle and Snoop Dogg, the Rolodex is thin.

That thinness isn’t apparent with opening song “Humility,” a blissed-out summer jam enlivened by Benson’s funky guitar. Snoop Dogg also returns to Gorillaz for a terrifically slinky portrait of “Hollywood.” And on the high-tempo “Sorcererz,” lead singer Damon Albarn’s vocal effects make him sound like an old blues legend.

Another standout is the mostly instrumental “Lake Zurich,” a disco throwback with some of the best cowbell ever recorded in this century. Seriously.

But it’s not clear what the poor state of Idaho did to deserve “Idaho,” a turgid, overwrought mess. “Kansas” seems like it was written in 10 minutes while absentmindedly waiting for a bus, and “Fire Flies” manages to be both clumsy and bland. “One Percent” is virtually unlistenable while “Magic City” is lazy and reveals the limits of Albarn’s natural voice.

Gorillaz manage to right this sinking ship by the last song, “Souk Eye,” which melds a good beat and interesting sonic textures with smoky vocals. Nice, but it’s too late for a messy album. (Albarn seems to concede this notion, singing at one point, “Everything that follows, I’m not responsible for.”)

“The Now Now” will test even diehard fans and reveal that the endless gimmickry from the so-called world’s first virtual band eventually can grate.
