The Post’s Chris Richards caught Apple’s first SXSW appearance last week: “... she sounded fidgety and freaked at Stubb’s Bar-B-Q on Wednesday. During new songs and old, she frequently replaced her plunging contralto with feral snarls. “You’re imaginary,” she told the audience at one point. “You’re not real.”

The postponement is an inauspicious start to a mini-tour that just got started on Sunday in Chicago with what Rolling Stone called a “manic” performance.
