"This is called the Lords of Summer." That's what James Hetfiled had to say when he introduced Metallica's new song which is hopefully going to be in their overdue 9th studio album.
The song was performed live in Columbia just a couple of days ago. There are already plenty of videos on Youtube of the performance. Musically it sounded like "Harvester of Sorrow", that is, it's a "heavy metal" song. Lyrically the song is about, well, summer.
