Two very different forms of early-’90s Chicago alt-rock will come together at venues around North America this summer. The Smashing Pumpkins are headed out on tour once again, and this time they’re bringing Liz Phair, who comes from the city but whose sound couldn’t be more different, as an opener. The Pumpkins tour has a name — In Plainsong — and it’s being billed as “an electro-acoustic evening.” The band is playing old seated theaters, and a press release promises “acoustic based music and electronic soundscapes.” Original drummer Jimmy Chamberlin, who rejoined the band for some shows last year, is once again a part of the lineup, as is Jeff Schroeder, the guitarist who joined in 2007. But the real draw, at least for some of us, might be the addition of Phair, who does not tour that often these days. Check out the dates below.
