The Oksana Mysina Theatrical Brotherhood plans to close its 2003-2004 season in the same way it opened — with a performance of “Quixote and Sancho” at the Vysotsky Center which will be preceded by a short outdoor concert by Oksana Mysina's rock band Oxy Rocks. The music starts at 7 p.m.; the two-hour show will start at approximately 7:30 p.m.
