Room 93 by Halsey

Room 93, Halsey's debut EP, came out on Astralwerks on October 27, 2014, not long after the New Jersey singer had turned a following built on self-released songs posted to social media into a record deal. It's a small, moody calling card: electropop in the dark, all synth haze and hotel-room claustrophobia, with a voice that sounds far more knowing than a first release has any right to.

"Ghost" was the main single, and it had legs; a new version arrived when the EP was reissued digitally in March 2015 and then carried over to her first full album, Badlands. A remix EP reworking "Hurricane", "Ghost" and "Trouble" followed, alongside a stripped-down "One Mic, One Take" set, and "Trouble" turned up in a promo for Once Upon a Time.
