Well I was taking a broader view than this puff piece I suppose. These persons I am referencing can speak happily of their love of jazz. . . but that doesn't erase dangerous loneliness. artistic career frustration, family issues (some induced by conflicts of political and religious ideologies), problems with substance abuse et al that are making them non-happy persons. Jazz won't save you from many unhappinesses even if it can be a salve or temporary release or escape.
