The Smashing Pumpkins are back – with spectacular intensity

You’d think that after performing for almost 2 1/2 hours and giving the audience three sets of encores, the Smashing Pumpkins would have run off the stage after their sold-out concert Friday night at the Rosemont Horizon. But when the house lights came on, there was a strange sight on stage. Singer Billy Corgan was still there, acknowledging the adulation of his cheering fans and obviously relishing the band’s triumphant homecoming.
