US rockers Metallica are releasing their first album in eight years.

The heavy metal group revealed details of Hardwired... To Self-Destruct -the long-awaited follow-up to 2008's Death Magnetic.

In a statement on their website, the group said their 11th studio album - which will contain two discs and nearly 80 minutes of music - was "a long time coming".

The music video for the album's first track, Hardwired, was also posted on YouTube.

Eight years is the longest period fans of the multiple Grammy winners have had to wait for a new album since the band formed in 1981.

The new album is set for release on November 18.
