Ethan Kath met Alice Glass when she was just 15. Impressed by her work with a local punk band, he hit her with a disc full of instrumentals. Alice wrote to a few of the songs and when she went to the studio to record them, the sound engineer secretly recorded her soundcheck. The track was aptly titled "Alice Practice" and went on to become the band's first official release.
