It's not often that you stumble across a songwriter whose lyrics both sound and read like poetry. When those lyrics are set to music that balances burning indignation with lilting tenderness, and delivered in a voice imbued with the spiritual passion and yearning of gospel and the blues, you figure you've chanced upon something special. And so it is with 23-year-old Andrew Hozier-Byrne, an Irish singer-songwriter and multi-instrumentalist from County Wicklow who goes by the name of Hozier.
