Circadian rhythms are the natural cycles occurring within a period of wakefulness and sleep, of light and darkness. Across the nine-song spectrum of Circadian, the newest full-length collection by singer-songwriter Letitia Vansant, her luminous voice mirrors the rich emotional quotient of her themes, breathing life into songs that balance contemplative compassion with righteous fury. Her lyrics are as personal as they are political. "You Can't Put My Fire Out" is a smouldering reflection on her journey of healing from her experience of sexual violence, while "Tin Man" is a subtle character study on cultural notions of masculinity.
