"Alvar" by Goldfrapp is a song that is open to interpretation, as it does not have a clear and specific narrative. The lyrics contain vivid imagery and metaphors, creating a dream-like and atmospheric atmosphere. The song seems to describe a longing for someone or something that is no longer present. The mention of autumn, sunset, and winter lights on the lake evoke a sense of change and passing time. The speaker feels the absence of this person or thing in their life, as indicated by lines such as "no boat no sign of you there" and "In the endlessness two worlds looking back at me now." The desire to "swim your silk black skin to the floor" can be interpreted as an intense longing or yearning for a deep connection. The mention of "lava moons" and a "song of hooves" add to the mystical and otherworldly imagery of the song. Overall, "Alvar" invites listeners to create their own personal stories and meanings based on the emotions and impressions evoked by the lyrics. It is a song that leaves room for individual interpretation and imagination.
