Avril Lavigne's next album, which she recorded and wrote with her new fiance Chad Kroeger of Nickelback, should be out at the end of 2012 or early in 2013. In an interview with Billboard, Epic Records Chairman "L.A." Reid says Lavigne just completed the record. "She worked with Chad Kroeger, who is now her fiance, and they did a really good record," says Reid, who added the album is currently in the mixing process.

On the heels of their summer release, Americana, Neil Young & Crazy Horse will release another album, entitled Psychedelic Pill, on October 30. Produced by Young with John Hanlon and Mark Humphreys, Psychedelic Pill was recorded right after Americana and features eight tracks, plus a bonus track. Due to the lengths of many of the songs, some of which were previewed during Crazy Horse's live performances in August, Psychedelic Pill will be released as a double-CD and as a triple-LP vinyl edition. Crazy Horse will hit the road again for a North American tour beginning on October 3 in Windsor, ONT.

Frank Ocean revealed on Twitter that John Mayer will perform with him on this weekend's season premiere of Saturday Night Live. Mayer played on Ocean's song "White" on the R&B singer's critically acclaimed new album Channel Ocean.

To mark the 20th anniversary of Countdown To Extinction, Megadeth will offer a two-disc reissue of the album, as well as a North American tour where they’ll perform it in its entirety.
