Crobot are back and ready to unleash a heavy, funked up slab of sludgery on you. The band just revealed their new song "Not for Sale," which you can check out in the player provided below.

The song kicks off with some heavy low end and aggressive drumming, later giving way to Brandon Yeagley's make-or-break vocal, which powers the chorus as he reaches his upper register. The vocalist told Noisey, who premiered the song, "['Not for Sale'] takes you into orbit around the sonic spectrum of our latest album and is an anthem for all of us who work hard enough to make our own luck. It's a cry to hold on to our own humanity, never letting anyone else manipulate our destiny. Who paid your debt to be here? No one ... and my soul is not for sale."

The song is the first piece of new music to come from Crobot's next album, the newly announced Welcome to Fat City. The band has been in the studio with producer Machine working on the disc, and they turned the effort to acclaimed engineer Alan Moulder for the mixing process. Look for Welcome to Fat City dropping on Sept. 23 via Wind-Up Records. And if you like what you hear from "Not for Sale," the song ironically is available for sale via iTunes.

Crobot are also cranking up the touring with their new album on the horizon. Look for them on tour with Sevendust this summer, as well as playing some festival shows in the coming months. See all their dates here.
