From the opening Mod nugget "I Can't Explain" (the group's first single), through burly hits such as "Who Are You?" and "Won't Get Fooled Again," to a moving suite of excerpts from the pathbreaking rock opera "Tommy" that served as the encore, the show was stirring and impeccably played. If it lacked the sense of barely contained chaos that once set the Who apart, it made up for that with the weight of history these songs carry - a weight which, handled deftly, feels like comfort, not burden.
