Los Angeles rockers Weezer – who won over fans throughout the last two decades with hits like “Buddy Holly”, “Undone – The Sweater Song” and “Island In The Sun” – are set to release their eighth studio album this September.

The as-yet-untitled disc will be the follow-up to Raditude, which only dropped in November 2009. According to a new interview with Weezer frontman/songwriter Rivers Cuomo in Connecticut’s News Times, the new album will have a distinct sound, the band supposedly ditching their much-loved indie power pop riffs for metal stylings.

“There’s definitely going to be more raw rock energy on this one,” Cuomo commented, when asked about the upcoming longplayer. “I’ve spent the entire morning trying to come up with a name for the record... How does Heavy Mental sound?”

Weezer released their latest track, “Represent”, last month, the song apparently an unofficial anthem to coincide with the 2010 FIFA World Cup. The band are also currently compiling a new collection of tracks from the Pinkerton era (1996), while back in April the “Tired Of Sex” singer released a live solo EP, titled Not Alone – Rivers Cuomo and Friends: Live at Fingerprints.

The new disc is (reportedly) set for release on Monday 13 September.
