The Pulse of Radio reports: The SMASHING PUMPKINS will commemorate their 20th anniversary with a series of special concerts, according to a post at the band's official web site. The post read, "To celebrate the band's 20th anniversary, SMASHING PUMPKINS will be playing select U.S. cities in August and September of 2008. No dates or cities have been announced but expect the band to revisit a few specific places that were missed during the last U.S. tour."Pitchfork Media reported that the PUMPKINS will play in Chicago, New York and Los Angeles, and that special guests may turn up at each show. The group is also said to be working on a DVD filmed during their two-week residency last summer at the Fillmore Theatre in San Francisco, the second of two residencies the band did to mark their reunion. The PUMPKINS also have plans to issue both older demo recordings and some new material later this year. The group is suing its former label, Virgin Records, alleging that Virgin used their name and music in a promotional campaign without their permission. Frontman Billy Corgan recently hinted that the band, who released 2007's "Zeitgeist" after a seven-year hiatus, will most likely put songs out in different configurations than the standard CD.
