Papa Roach and In This Moment will tour together this fall as part of a larger bill that also includes Five Finger Death Punch and From Ashes to New, but the two bands decided to get that "crossover" thing out of the way much sooner. In This Moment's Maria Brink appears on Papa Roach's current single "Gravity," and she joined Jacoby Shaddix and crew onstage in Moline, Ill., for the live debut of the track. Fan-filmed footage featuring a portion of the performance can be seen in the video above.

Last fall, bassist Tobin Esperance told us, "Maria just worked out great, she has such a rad raw chick voice and she really got to do something. I feel like she did something different on this song, it was a different song for us too."

As for the inspiration, Jacoby Shaddix stated, "That’s a raw nerve, too, man. I always want to put myself out there in the music and this song just more so than really ever. It doesn’t really necessary paint me in the best picture as far as the cliche rock guy gives himself to the rock and roll excesses story. But we went through that in our relationship, I failed as a husband, as a father, as a lover, as a friend to her and I just wanted to write a song about that brokenness and how somehow she sees something in me that I didn’t see in myself at times. She loved me when I couldn’t love myself."

The band recently debuted the video for "Gravity" and Brink reprises her role in the clip, serving as the female on the other side of the relationship dealing with Shaddix's excess. Check it out here.
