Rising pop queen Billie Eilish doesn’t even have a full album out yet — and still the 18-year-old singer drew max capacity at the South by Southwest Uber Eats House.

With an impossible line that wrapped around the building, Eilish’s performance was in high demand. At least 100 people didn’t make it inside. Though murmurs throughout the line outside the venue revealed many fest-goers didn’t know much about Eilish’s music, curiosity was high.

“She’s kind of a big deal,” one person in line said.

Set to release her debut LP “When We Fall Asleep, Where Do We Go?” on March 29, Eilish’s career took off following her debut single, the dreamy, synthy “Ocean Eyes” in 2016. While Eilish has a writing part in most all of her music, her older brother and musician Finneas O’Connell produces her work. If Eilish’s SXSW set is any indication, this is a family on the path to dominate the radio.

We called it at last year’s SXSW, and we’ll say it again — Eilish is on her way to being very, very famous.
