“I was worried,'' Victoria Williams says with a laugh as she speaks about her new album, Sings Some Ol’ Songs,“I've never put out a record of songs I didn't write.'' Sings Some Ol’ Songs may be a decidedly different enterprise for Williams, who since 1987 has captivated the music world with her distinctive songwriting and keening vocal approach, but it still has the same attributes she's demonstrated on her six previous albums, namely an ability to take a song, any song, and deliver it a manner so individualistic that it becomes hers alone.
