I have no reason to doubt the projections of Disney Hall as a sonic marvel to match the splendor of its design, but I cradle my ancient ears in cotton every night to keep them in shape for “Judgment Day, the Disney Version.” I don‘t, in any case, envision the Dorothy Chandler Pavilion as a triumphant survivor. The recent sale of the Ambassador College campus does provide a glimmer of hope -- however faint -- for its long-lamented, acoustically splendid auditorium. But the buyer, Legacy Partners of Orange County, is in the realty business, not an enlightened concert management. It cannot have escaped its notice that the Ambassador campus -- a handsome property handy to freeways, thriving Old Pasadena, museums, etc. -- is a real estate bonanza like few others. Does an altruistic soul still exist, willing to maintain that fine performing space in its merited glory, rather than as a pile of condos?
