Rivers Cuomo had never seen an episode of the surreal kid’s show Yo Gabba Gabba! before, but that didn’t stop the Weezer frontman from sporting a giant purple Spider costume and jumping around a stage filled with overgrown grass and giant acorns for his band’s performance of the original Gabba song “All My Friends Are Insects.” “It’s awesome here,” Cuomo told us during the recent taping (the show will air next year on Nick Jr.). “I love giant open rooms with tall ceilings. But here they have all this foam scenery and interestingly painted backdrops. It’s a cool fantasy land I’d like to inhabit.” After the jump, check out our exclusive behind-the-scenes footage of the band taping their performance, then let us know what you think about the band’s new tune (and costumes!).
