Cassie Henderson's musical journey began with a spark that quickly became a wildfire. Her single "Whatever" in 2023 wasn't just a song—it was a statement. For 12 consecutive weeks, the track dominated New Zealand's airwaves, signalling the arrival of an artist unafraid to turn personal pain into raw, compelling music.

The "Chronicles of a Heartbroken" trilogy emerged as her bold narrative framework – three EPs that map the intricate emotional terrain of heartbreak. In 2024, "Seconds To Midnight (11:59)" pushed her breakthrough further, breaking records on Shazam and holding the charts for 15 weeks. This wasn't just commercial success; it was a testament to her ability to capture a generation's unspoken emotional landscape.

Live performances revealed another dimension of Henderson's artistry. Her nationwide tour and festival sets drew audiences who weren't just passive listeners, but active participants in her musical storytelling. Fans travelled significant distances, drawn by a performer who transforms vulnerability into power.

With millions of streams and a fiercely loyal online community, Henderson has created more than music – she's crafted a cultural moment. As she prepares to release the Blue Chapter in 2025, completing her trilogy, she continues to challenge how we understand heartbreak: not as weakness, but as a complex, nuanced form of human experience.
