Clutch recently covered Cactus' version of "Evil", which itself is a cover of a Willie Dixon song. The song is a part of their Weathermaker Vault Series that will be periodically rolled out over the course of this summer. The series will be covers of other artists, as well as Clutch covering their own material.
You can now watch Clutch performing "Evil" at Download Festival, and you can also catch Clutch on tour with Killswitch Engage this summer, where I'm sure you'll also hear the song.
