Smashing Pumpkins Add More Theater Dates

update: Smashing Pumpkins have beefed up the itinerary for their April-May tour of U.S. theaters, adding 13 additional dates. The band is supporting its new album "MACHINA/the machines of God."

Tickets for the newly announced dates are scheduled to go on sale Friday and Saturday (3/17-18). The band's previously announced concert dates in St. Louis, Milwaukee, and Chicago have sold out, but tickets were still available for the remainder of the dates at press time, according to the band's publicist.
