Halsey's debut EP, Room 93, dropped in October 2014, and some of her biggest songs solidified their place in the hearts of Tumblr users everywhere. The next step was touring the album, and making sure the right people heard it. South By Southwest is usually a huge event for most up-and-coming acts, but it was the biggest for Halsey: She was the most tweeted-about artist at the festival, beating out Miley Cyrus, Cody Simpson, Run the Jewels and more. The buzz made sense: Her handful of performances couldn't be missed (see photos here), and her interviews showed promised of a candid, intelligent, young pop icon.
