For 20 years now, Billy Corgan, Jimmy Chamberlin, and Smashing Pumpkins have lifted spirits with dreamy pop, tortured souls with mechanical metal, and blown minds with artsy psychedelic rock. As a statement of where they are now and where they’ve come from, the band is playing two special shows at Constitution Hall next week, each one with a completely unique set. Be happy, be sad, be angry; just make sure to be there, as one of the most unpredictably amazing bands gives you two of the “greatest nights you’ve ever known.”
