While it’s been thrilling to return to live performances, much of what I’ve seen had a sense of compromise. Happily, nothing felt second-best about Litvak Dance’s performance on August 28. Sadie Weinberg, who launched this North County company just three years ago, is a powerhouse networker. She recruited two guest choreographers to create work for the company: New York-based Rebecca Margolick, one of Dance Magazine’s “25 to Watch” this year; and Texas-based Joshua Manculich, who’s made dances for companies around the country.
