If there’s one thing to say about the Black Keys‘ Patrick Carney, he doesn’t pull punches when talking about other bands. In a new interview, the ever-candid drummer gives an outline for the Akron, Ohio, duo’s next album and slams “reunion tours” that have missing pieces, specifically Black Sabbath and Van Halen.

Whether he’s calling Nickelback “watered-down, post-grunge crap” or exhibiting confusion at the popularity of Electronic Dance Music, “I don’t know who listens to that kind of music, instrumental versions of LMFAO or whatever,” Carney has displayed an almost unnatural ability to speak his mind. Sometimes, it’s almost as if he has been afflicted by the same hex that was placed upon Jim Carrey’s character in ‘Liar, Liar,’ except Carney seems to have made peace with it.

Speaking to Rolling Stone, Carney detailed some of the the things on the Keys agenda that he was excited about. One of them being the band’s headlining performance at Lollapalooza, where Black Sabbath is also set to headline. “I love Black Sabbath,” said Carney. “But I don’t know if I’d want to watch Black Sabbath without Bill Ward.”

Carney further explained that he has “no interest in seeing bands with partial lineups,” after recently seeing Van Halen without original bassist Michael Anthony, an experience he described as a “f—ing bummer. Like what the f— is the point? I mean, sure, Eddie Van Halen’s son is a pretty good bass player and he’s a 20-year-old kid and that’s cool, but like, what the f— is that? That’s f—ing retarded. If someone is able to be in a band for 30 years and then people are okay with replacing him with a 17-year-old, they’re obviously motherf—ing a–holes, right?” Carney finished his rant by saying that he does enjoy some classic Van Halen, but did not enjoy the show “at all” and thinks some of their catalog is “exceptionally awful.”

As for the rest of the Black Keys’ summer, Carney confirmed that new music is still a part of the gameplan. “We’re going back in the studio in July. We’ll have a couple weeks to start the next album then,” said Carney, further saying they hope to release the album in 2013. “We don’t know when we’ll be done but we’re starting it in July. We might not finish it until March since we have to tour so much but we’ll see. We don’t know what’s going on. After July, we’ll be able to know how long it’ll take.”
