We're calling it: In the rock 'n' roll history books, Gary Clark Jr. will have two eras: before 'This Land' and after it. Just get a load of the fire and fury that opens the title track: 'F**k you, I'm America's son/This is where I come from,' he snarls. Clark's rage is partially directed at his racist neighbor in Austin, Texas, who can't seem to accept Clark's sprawling 50-acre ranch, as well as a few experiences from his childhood. 'I had a few situations down there with some racism, and some Confederate flags, and people calling me out of their trucks, all that kind of stuff,' he told Beats 1 host Zane Lowe. 'I had a beat that I laid down but didn't have any lyrics over it and it just came to me. I just went in there and fired off.'
