Metallica "Lords of Summer" (First Pass Version)

Metallica 'Lords of Summer' (First Pass Version)
Metallica are evidently pretty excited about their new song "Lords of Summer." Already this year, the divisive metal legends have performed the song live and shared a "garage demo," and now they've released a so-called "first pass" studio version.

Clocking in at almost eight and a half minutes, it's a heavy epic filled with headbanging riffs, grizzly growls and full-throttle thrash energy. Since this is labeled as a "first pass," we might see a cleaned-up version on Metallica's next album. That being said, this is an officially approved version, since it's available on iTunes.

Hear it below.
