Any theater that can produce the cornball lovefest Steel Magnolias in the upstairs auditorium while running David Mamet's darkly profane Glengarry Glen Ross downstairs in the basement deserves a huge round of applause. But that bit of artistic (and marketing) genius was just what came at the end of the Alley Theatre's fabulous year. The rest of the season included unforgettable performances in shows such as The Exonerated, a deeply disturbing play about the death penalty; and The Crucible, a classic by the late Arthur Miller that paid wonderful tribute to one of America's greatest playwrights. There was also a loopy script by Steve Martin called The Underpants, of all things, and a hilarious import from a group of California Latino iconoclasts called Culture Clash in AmeriCCa. Season ticket holders had to be thrilled at their good luck.
