“To many minds, the merger never made sense. Looked at solely from the perspective of the New York Philharmonic, the primary advantage was obvious: instead of being a tenant in the acoustically challenged Avery Fisher Hall, the orchestra would have become a co-resident at America’s most storied and acoustically excellent auditorium. But it was much harder to see how Carnegie Hall was supposed to benefit from the merger, unless you viewed it essentially as a business venture that would have combined two endowments and two subscriber bases at a time of economic uncertainties.”
