PREVIEW Have you ever seen a string quartet perform in the air specifically, a violinist play while hoisted on the shoulders of some dancers? Or have you witnessed a violist getting his hair done while concentrating on an intricate melody? If you missed the delicious collaboration between Janice Garrett and Dancers and the Del Sol String Quartet last April, here's your chance. StringWreck is perhaps the most original and unlikely piece of collaboration between music and dance to hit the Bay Area. And it's all homegrown. But more than that, the work is as serious as it is irreverent; it's imaginatively conceived and realized without an ounce of self-conscious bravado or pretense. These musicians and dancers are excellent at what they do independently, but together they likely have stretched in ways as unexpected to us as to themselves. Garrett and her artistic and life partner Charles Moulton a man of uncommon wit handled the choreography. Del Sol String Quartet chose music from 20th-century icons such as Gyorgyi Ligeti, George Antheil, Murray Schaefer, Astor Piazzola, and the old 18th-century man himself, J.S. Bach no sugary pap here. In April the piece lasted about an hour. These performances, courtesy of Jewels on the Square, are a little shorter than most, but you get the added value of chalk artist Tracy Lee Stum, who will draw the set and it's all free.
