According to Songfacts, Lewis found it hard to think of a title for the album straight away, but when it finally came it made absolute sense. Echo not only reflects the record's 'epic and ethereal' sound, but also appeals to Leona's innate love of fantasy and otherworldliness. "Echo was a nymph in Greek mythology and she fell deeply in love with a boy who didn't return her love," she recounted. "But she loved him so much that she pined away till only her voice remained. That's a really sad and beautiful story."
