Yiddish words and sayings permeate English slang. We schlepp our schlock. Call one other schmoes, schlemiels, schmoozers and schnooks. But there's nothing schmaltzy about the inherent musicality of the Yiddish language. A Traveling Jewish Theatre goes beyond its day-to-day usage and explodes stereotypes about the dialect in Diamonds in the Dark: An Exploration of Yiddish Poetry. The San Francisco-based ensemble captures the lyrical passion of this century's Yiddish poets, setting movement and the spoken word to a jazzy, neoclassical musical score. The poetry bears witness to mystical, erotic and political themes to the rhythms of Yiddish and English speech. 8 p.m. at the Jewish Community Center, 5601 South Braeswood. Call(713)729-3200 for information. $18; $10, students and seniors.
