Just the Beginning, that she called "more produced ... really the same sound ... [but] less acoustic" than her debut EP. She told an interviewer for
Rookie magazine about how her process changed for the album, writing songs "on demand" with a collaborator: "I've never done this before; it's kind of weird to go into a room with usually a 30-year-old man and just be like 'Oh, let me open up about my life to you and write a super personal song!'" In June, she participated in
VidCon's opening show,
YouTube OnStage, in The Arena at
