Dave Grohl says Nirvana’s “In Utero” likely rubbed off on both Weezer’s “Pinkerton” and Bush’s “Razorblade Suitcase.”

“An unknown band gets a record deal, goes into the studio with a producer and they make an album and it does really well and then they feel kind of weird about it because maybe it didn’t sound the way they wanted it to sound.” Grohl explained during his appearance on the “Conan O’ Brien Needs a Friend” podcast. “And then they go in to make their second record and they’re like, “Well, now this is what we really sound like.”

Grohl went on to say, “So, Weezer did it with their album ‘Pinkerton,’ which is a f**king amazing record. The first Weezer record has a bunch of hits and they become really popular. Then they go in to make their second record and it’s kind of like their ‘In Utero.’ Another band [is] Bush. Bush is a band that gets really popular and has this produced record. Then, they decide, “No, wait, f**k that. Now that we’re big, we get to do the thing that we really want to do, so we’re going to go in and make an album that’s raw [in] the way it sounds.”

Nirvana recently celebrated “In Utero’s” 30th anniversary by releasing a box set that includes 53 previously unreleased tracks, a 48-page book, a 20-page fanzine, and other goodies.
