Emily Marcia Armstrong is an American singer. The co-founder of Dead Sara, she joined Linkin Park as the band's new lead vocalist in September 2024, following the death of their long-time lead vocalist Chester Bennington in 2017. Armstrong was born in Los Angeles. Her parents were prominent members of the Church of Scientology, and she was raised as a scientologist. She started to write songs and play guitar when she was 11 and began to sing when she was 15. She dropped out of high school; she knew she wanted to be in a rock band when she picked up the guitar and had no interest in pursuing anything else. In an interview with the El Paso Times in 2012, Armstrong said music was the one thing that kept her motivated in life.
