It seems like only yesterday listening for the first time to the "Battle of Evermore" from Led Zeppelin IV when the female voice on this duet with Robert Plant cast a spell which has proved enduring. It was the only song Led Zeppelin ever recorded with a guest vocalist although Sandy Denny went on to produce even greater glories. 1971 saw both the release of the Zeppelin classic and Sandy Denny's first solo album "The North Star Grassman and the Ravens" here given the deluxe treatment by Island records in the form of the original record now digitally remastered, plus bonus tracks including already released BBC recordings, 5 rare demos that are on the humungous and expensive box set and one unreleased recording: an instrumental version of Lord Bateman.
