Having focused on film work for some time, Lisa Gerrard returned to creating standalone albums with Immortal Memory, the first of many albums she would work on in collaboration with various creative partners in the 21st century. Irish synth musician Patrick Cassidy had already released a number of albums on labels like Windham Hill before meeting Gerrard via work on the Gladiator soundtrack; here they create slow, achingly lovely performances, including adaptations of old Gaelic songs and poems by Yeats and Milton that are captivating.
