Slipknot fans have been trying to figure out the true identity of “Tortilla Man,” Slipknot’s new percussionist, who replaced Chris Fehn. The fans seem to have sufficient evidence that the new member is Michael Pfaff and a new unmasked photo with other band members, along with a signature in a sign-in book seems to confirm this.

The photo was snapped after Shawn Crahan, Jay Weinberg and “Tortilla Man” visited the Postojna Cave Park in Slovenia during their European tour. The park shared a series of photos on Facebook.

In the image of the guest book, you can see the signatures by the band members. One signature seems to say “Pfaff.” Pfaff also plays with Crahan in a band called Dirty Little Rabbits.
