For all their rat-in-a-cage rage, Smashing Pumpkins can unspool epic drama with artful restraint. Digging into their catalog reveals quiet wonders, like the slinky, industrial groover "Eye" and the softly twanging "To Sheila," which is built around a minimal acoustic riff. Even their bleariest rock opera, "Glass and the Ghost Children," centers on an eerie calm within a storm.
