After teasing fans with a 30-second clip last week, Avenged Sevenfold have unleashed the full version of their new single, 'Hail to the King,' which is the title track off their upcoming album, due Aug. 27.

Back when Avenged Sevenfold had started working on the new album, singer M. Shadows suggested the disc would have a classic metal feel, and the song 'Hail to the King' definitely lives up to that sentiment. Starting off with a some fancy fretwork over a monster riff, the track explodes into a full-on metal assault with Shadows delivering James Hetfield-like vocals over Black Sabbath-like guitars in the verses followed by a very melodic chorus.

The album is the first A7X disc to feature new drummer Arin Ilegay, and he delivers a thumping beat throughout the single. But it's axemen Synyster Gates and Zacky Vengeance that take the spotlight on the guitar-heavy track.

Listen to Avenged Sevenfold's 'Hail to the King' above, and be sure to pick up the album by the same name when it drops on Aug. 27.
