金枝欲孽的插曲叫什么

这是一部关于民谣的纪录片，但歌里唱的不是流浪也不是远方，而是脚下实实在在的土地和身边活生生的人。七组民谣音乐人像植物一样扎根在故乡的泥土，感受着时代的冷暖与挣扎，顶着满身灰尘，盛放出颜色不一样的花朵。。Dallas is a one-man killing machine on a mysterious rampage. His attacks on biker gangs and meth labs anger the Vegas mob boss who's holding Dallas's girlfriend hostage. But who is Dallas working for? Even torture won't make him talk...and he won't stop until justice is served.。
