Metallica have FINALLY released (what they’re calling a) "garage demo" of their new song Lords Of Summer which they unveiled at their show in Colombia last weekend

It's not certain whether it'll appear on the long-awaited follow-up to 2008′s Death Magnetic, which is slated for (*snicker*) next year - but UK fans will be able to hear Metallica perform it during their appearance at Sonisphere in July.

Meanwhile, bassist Robert Trujillo says Metallica is moving forward by staying grounded:

"The energy and the spirit of the first five albums is special - and it helps us write music now that still has that flavour, without leaving behind what we are now."
