1. This fall the Pennsylvania Academy of the Fine Arts mounts an exhibit of work by a former outlaw graffiti artist who is now an art-world insider. “Steve Powers: The Magic Word” showcases the artist’s recent foray into narrative painting, after a history of creating illegal outdoor murals under the alias ESPO. You can view Powers’s work—which is informed by signage and based on autobiography and urban myth—from October 20 through January 27, 2008.

2. Artworks that generate sound are often difficult to present in one venue, since the sounds compete with one another, but curator Christian Marclay—who is also an artist and musician—is up to the challenge. “Ensemble” features interactive pieces, some of which are triggered by motion detectors. See—and hear—these audio works at the Institute of Contemporary Art, University of Pennsylvania, through December 16.

3. Alfred Stieglitz altered the history of photography with his impeccable craft, his devotion to the ideal of the medium as an art form, and his promotion of work by important photographers in his galleries. “Alfred Stieglitz and the Philadelphia Museum of Art” is a carefully curated selection of 40 masterpieces from the museum’s collection of 600 images by the seminal photographer, and includes prints donated by his wife, Georgia O’Keeffe. At the Philadelphia Museum of Art through January 31, 2008.

4. In perfect time for Halloween, a spooky surprise from the Rosenbach gives museumgoers a chance to see author Bram Stoker’s working notes and research for his well-known gothic horror novel. A reading corner and costume area for children is sure to please younger visitors. You can study this creature of the night, and the man who created him, through November 4.

5. When central Panama’s Rio Grande de Coclé changed its course at the turn of the 19th century, a bevy of treasures awaited discovery. More than 120 pre-Columbian gold objects and nearly 150 artifacts more than 1,000 years old are on display in “River of Gold: Precolumbian Treasures from Sitio Conte.” To learn more about the ancient culture of this region, head to the University of Pennsylvania Museum of Archaeology and Anthropology until December 16.

"Top Five Philadelphia" comes to ARTINFO from the fall 2007 issue of Museums magazine.
