FILE UNDER FOO FIGHTERS:

Foo Fighters have finished their eighth album.

Record producer Butch Vig revealed the news on Twitter this past Tuesday. “We are officially done with the new Foo Fighters album. 23 straight days mixing! IT’S EPIC!!!,” Vig tweeted.

The album, titled Sonic Highways, is due out in November, but an exact release date has not been announced.

Foo Fighters is marking their 20th anniversary with the HBO documentary Foo Fighters Sonic Highways. The series chronicles the eight-city recording trek that produced the new album.  The documentary airs in October.

FILE UNDER SLIPKNOT:

A fifth Slipknot album teaser has joined its predecessors online. The clip is short and dark and features similar characters to those in the earlier installments.

In what could be a sign that the band senses fans’ growing impatience with the tell-nothing teasers, Slipknot frontman Corey Taylor posted a cryptic tease Tweet –“Heheh. Friday.” — hopefully signifying that some concrete information is forthcoming.

Slipknot has been working on the new album — its first studio album since All Hope Is Gone in 2008 — since February, and its progress has been marked by drama. It’s the first without drummer Joey Jordison, who was fired late last year for undisclosed reasons, and without bassist Paul Gray, who died in 2010 of a drug overdose. Though guitarist Jim Root worked on the new album and remains a part of the band, he was asked to leave Slipknot side project Stone Sour two months ago under mysterious circumstances, in a decisions which Taylor would only describe as “what’s best for both bands.”

Stay tuned, ‘Knot fans…maybe there will be reason to celebrate this weekend.
