"All Souls Night" begins the album, with dance-like rhythms and McKennitt's wonderful voice singing about the Celtic New Year. Other features include a musical setting of Tennyson's "Lady of Shalott", which, while not as sophisticated as Noyes' "The Highwayman" on The Book of Secrets, is an enchanting listen. There's also an interesting rendition of "Greensleeves" and the Spanish-flavored "Tango to Evora", as well as the haunting "Courtyard Lullaby" and the wistful "The Old Ways". A setting of words from Shakespeare's Cymbeline closes the album, which focuses thematically on life, death, and the borders between them. --Genevieve Williams
