Los Angeles Times August 4, 1991, Sunday, Home Edition "THE YEAR OF THE HORSE" SINEAD O'CONNOR By ROBERT HILBURN O'Connor's move from Los Angeles back to London was probably the best thing the Irish singer-songwriter could have done for her career in the United States, because pop audiences will now tend to encounter her through her music rather than her media outbursts. Her music carries the same passion and conviction of her public remarks, but the music is framed with such sureness of craft and depth of passion that it is hard not to be moved. In this hourlong video drawn from two European concerts last fall, director Sophie Muller eloquently captures O'Connor's art. And O'Connor shows that she does have a sense of humor: The video package is dedicated to the man who criticized her for not letting the national anthem be played before one of her concerts last year in New Jersey: Frank Sinatra.
