Metro, December 10-17

This week, an interview with John Zak, half the cast of the Walnut Independence Studio on 3's production of "Greater Tuna"; a piece on the Whirling Dervishes of Istanbul, at the Annenberg Center (issue not online); and, just because it's the last piece before the holiday so why bother giving it its own post, a piece on Relache's annual Rittenhouse Square performance of Phil Kline's "Unsilent Night" (credited to Brendan Huffman, but I swear I wrote it).
