LA Phil Live: Dudamel conducts Mahler should have been a wonderful evening, but something was wrong with the surround-sound at the Regal Union Square Cinema. Although the interviews and previews with musicians from the 2 participating orchestras were fascinating & heart-warming, the broadcast of the actual performance was a disappointment. John LIthgow, as the host, was a bit too enthusiastic for my taste; but that's not the reason for my "So-So" review.
