The Smashing Pumpkins may be kicking off their 20th anniversary tour on Halloween, but frontman Billy Corgan tells Spinner that the band is already looking forward. "We started writing some of the songs [for a concept album], but it's so overwhelming," he says. "Honestly, what we're actually trying to do is create a very new media-based way to interrelate a visual and a long song cycle. That's really challenging. We're in way over our heads at this point."

But first things first: the anniversary tour. "We really treated it as a special one-time event, so we have horns, a violin player and we're playing a lot of songs we wouldn't normally play," Corgan says.

In addition to the rare songs, the band will be doing two-night stands in select cities, like New York, Boston and L.A. And fans who pony up for both shows are guaranteed totally different sets, though Corgan admits that presents a problem. "The two-night format of playing two totally different sets is really challenging because what the hell are you gonna close Night Two with if all the best stuff is in night one?" he says. "We're really excited about playing the song 'Sunkissed' off our EP, 'American Gothic' -- it's about a six-minute long song. It's very gentle and we're playing with the horns and everything. It sounds great, but it's the type of thing that'll totally kill the crowd and everybody starts throwing s---."
