The crowd of teens in T-shirts and jeans is punctuated by a few in leotards and others with large instrument cases slung over their shoulders. Some practice their fancy footwork in the hallways, while others warm up their vocal chords by singing a few bars.

In what was once a quintessential blue-collar part of town, students now learn to pirouette, write music and paint while they master their academic subjects.
