Virginia Tech’s new Center for the Arts doesn’t open until Nov. 1 but advance season ticket sales are strong. About a third of the $100 million center’s seating capacity for 25 scheduled shows already has been sold. The main theater’s maximum seating is 1,260. There also is a smaller venue called “The Cube” that can seat about 100. Spokeswoman Susan Bland tells The Roanoke Times that the center has sold the equivalent of about 5,400 tickets through subscription packages so far. Tickets to individual performances will go on sale Aug. 6.
