Legendary rockers KISS unveiled their brand new stage show earlier tonight (Saturday, June 1) at the opening concert the European leg of their "Monster" world tour in Stockholm, Sweden.Video footage of the "Psycho Circus" performance from the Stockholm gig can be seen below. "It's really great," KISS frontman Paul Stanley told VH1 Radio Network's Dave Basner about the new tour. "You know, for so many years, we've talked about a new stage show and basically what we've been doing has been an extension of the old stage show. So people would sometimes come and, obviously, the band does a great show and it's great to be there, but some people would say, 'Gee, it doesn't look that different.' This is a completely different stage, it follows a really great theme, the lights are like nothing you've ever seen before." When pressed for more details, Paul said, "Um… I hate to give anything away but when you see first photos of this new tour, and we're headlining festivals all over Europe, I think people will be blown away by what we're doing onstage." During a recent question-and-answer session with a group of fans, KISS bassist/vocalist Gene Simmons revealed that the new stage includes a 70-foot screen and a giant spider that shoots fireballs out of its tentacles. "This spider is just beyond anything you've seen," he said. "It'll be able to be flat and come up and walk almost to the front of the stage. It's the most amazing thing I've ever seen." He added: "We’re gonna levitate and go 30 rows into the audience. Oh — and play songs! It'll be the best tour yet, you'll see." KISS recently completed an Australian tour with very special guests MÖTLEY CRÜE. "Monster", the 20th studio album from KISS, sold 56,000 copies in the United States in its first week of release to land at position No. 3 on The Billboard 200 chart.
