'Love Potion' casts a haunting spell... poetic production directed and designed by Mitisek cast a spell of their own, Mitisek's austere production is like a mystical ritual that exists beyond time. The singers, garbed in simple modern attire, bear wooden poles that suggest variously spears, oars, trees and a headboard for the dying knight Tristan. The performers rise from seated positions to voice their parts, while video projections of sea, sailcloth, forest and storm play across the theater screen behind them.
