Big Nazo is an international performance group of visual artists, puppet performers, and masked musicians who unite to create bizarre and hilarious larger-than-life sized characters, environments, and spectacles from Providence, Rhode Island. Renegade circus family contortionists, a rowdy rodeo horse, a giant three-eyed robot percussionist, break-dancing police officers, Mountain Trolls, blob-like GO-GO Dancers, a charismatic lab rat and his giant man-eating chia pet are just a few of the characters, environments, and spectacles that create an irreverent musical Commedia full of irresolvable conflict, ridiculous dancing and an epic battle with the forces of chaos. Their innovative mask & puppetry techniques combine stand-up comedy, Sci-Fi, Go-Go dancing, daredevil stunts, soap opera hysterics and professional wrestling with live rock & funk music and audience-interactive improvisation  .
Big Nazo's audition in Episode 906 consisted of a member of the group wearing a dog mask and giving directions for the two other members of the group portraying big-headed aliens to follow. Howard Stern, Heidi Klum, and Howie Mandel buzzed the act. Howard, Heidi, Mel B, and Howie all voted "No," eliminating the group from the competition.
