In his first year with the Boston Symphony, there is no question that James Levine has made a distinct mark on the city’s musical life, garnering praise but also creating controversy with his devotion to complex and dissonant music. “Whether he can carry the audience along with him is still an open question, although one is tempted to say that if he can’t, nobody can. If he is driving some people out of the hall, there is a gratifying new component of young faces and prominent members of Boston’s musical community who didn’t make a habit of attending [former BSO director Seiji Ozawa’s] concerts.”
