McKinney + Silver held an open house at its new offices in Durham, N.C., Oct. 28 to celebrate its 35th year in business. The event featured Benjamin Zander, music director of the Boston Philharmonic Orchestra, who gave a motivational speech about the “Art of Possibility” to the more than 160 employees and invited guests. James Surowiecki, financial columnist for The New Yorker, spoke about his new book, “The Wisdom of Crowds,” and cellist Matt Haimovitz performed. M+S moved earlier this year from Raleigh, N.C., to space in the former Lucky Strike plant in Durham. Guests included top executives from Audi, the shop’s largest client, who thanked M+S for its more than decade of advertising their cars. The party was aired live in Times Square on the Nasdaq screen. Nasdaq is a McKinney client. Liz Paradise, agency gcd, is seen here with John Sweeney, professor of advertising, and Tom Bowers, senior associate dean, both of the University of North Carolina School of Journalism and Mass Communications.
