How Can I Sleep With Your Voice in My Head documents a-ha's 2002 world tour in support of Lifelines. The album's 14 tracks were compiled from various performances recorded over the tour's final six weeks. Rather than focusing on newer material, the album gives almost equal due to the seven years between Hunting High and Low and Lifelines. The years have clearly been good to a-ha, as they present here both a youthful rock swagger and a mature sense of confidence.
