Sales were badly underperforming in some markets.

The inaugural Zooma tour, which was to be headlined by Trey Anastasio and Ben Harper, has been canceled. Zooma was scheduled to run from June 13 to July 31 and feature a high-profile cast of supporting acts, including the Black Keys, Galactic, Gomez, Medeski Martin & Wood and Jurassic 5.

"Unfortunately, ticket sales weren't what anyone expected," Zooma producer Jonathan Mayers tells "We went into this hoping to do a whole concourse activity and really present a full entertainment experience, and because of where we are with sales we aren't be able to deliver that. So we all mutually agreed to pull the plug."

Mayers, who is also one of the producers of the annual Bonnaroo Festival in Tennesse, says Zooma wasn't a total stiff. "But it was definitely far below everyone's expectations, as tour producers, management and the promoters, which was kind of surprising." Asked if he had any idea as to why the concept didn't take off, Mayers says, "It's really hard to say. I just think at the end of the day the synergy just didn't work like we thought it would -- it just didn't resonate with the audience. Sometimes you just don't know until you try something."

That said, Mayers says Zooma's failure will not preclude Bonnaroo producers from trying other new concepts. "Our company is going to continue to take risks, and sometimes they're going to be successful and sometimes they're not going to be successful," he offers.

"But we're not going to stand on the sidelines and wait for something to happen," he continues. "You take good calculated risks, you go with your gut and the people around you, and that's what we did. And we're going to continue to take risks and go after other ventures. We're just getting started. We're definitely doing other things, and we're going to do other things this year."

Fans who purchased tickets through Anastasio or Harper's Web sites, as well by Ticketmaster's phone or online outlets, will receive automatic refunds. Tickets obtained via other locations will be refunded at point of purchase. Anastasio's Web site says the former Phish guitarist is already plotting a new summer tour itinerary. It is also hosting a clip of Anastasio's new band from its first studio session in Nashville earlier this year. Zooma was the second major jam-band tour to be announced for this summer.

As previously reported, the String Cheese Incident will headline the BIG Summer Classic 2005, which will launch with shows July 2-3 at Red Rocks Amphitheatre in Morrison, Colo. Big Summer Classic producers say their tour is still on and selling well. "We're kickin' ass," String Cheese Incident manager Mike Luba tells "We're projecting that almost everywhere will sell out. But we're playing 10,000 seaters, not 20,000 seaters. We feel like or cost is fair to the promoters, and the ticket prices are fair to the kids."
