In Brief

* * * Sinead O’Connor, “Am I Not Your Girl?,” Chrysalis. O’Connor is certainly fearless. First, she accuses the record industry of promoting false and materialistic values. Now, the Irish singer-songwriter moves into mainstream pop for her versions of songs identified with such singers as Billie Holiday and Ella Fitzgerald. “Girl” is not an essential work, but in the most affecting moments O’Connor, working with an orchestra, reveals refreshing touches of innocence and tenderness that add to our understanding of her as an artist.
