Cat Janice, Singer With Cancer Who Left Her Son a Dance Track, Dies at 31

Cat Janice, a singer and songwriter who released a buoyant pop track from hospice that galvanized her thousands of supporters online to sway, and even groove, in the face of tragedy, died on Wednesday at her family home in Annandale, Va. She was 31.

The cause was sarcoma, according to William Ipsan, her brother.

The singer and multi-instrumentalist, whose legal name was Catherine Ipsan, started writing music as a teenager and released it throughout her 20s. But “Dance You Outta My Head,” which she shared on social media alongside candid discussion of her grueling cancer treatments, quickly became the biggest hit of her career. Over disco-inflected guitar and exuberant strings, she sang about “dancing on the edge of disaster.”

Ms. Ipsan released the song on Jan. 19, a few days after entering hospice care. The song caught fire as her health outlook darkened, with social media users — including celebrities like Jason Derulo — leaving messages of support.

It became a common soundtrack on TikTok after Ms. Ipsan encouraged her followers to stream the song as a way of supporting her 7-year-old son, Loren, after her death. “I am leaving this song behind for my son,” she wrote on TikTok. In another post, she said she had “changed all the rights from my songs so every presave and every stream goes to Loren.”

The song has been used in more than two million TikTok videos and became the singer’s first song to enter the Billboard charts.

“I’m praying my story isn’t over yet,” she wrote in a post on her birthday, the day after the song’s release. “But if it is, this is a pretty incredible way to say goodbye.”
