Originally from Brooklyn, New York, Miller moved with his mother to New Jersey after a brief separation of his parents, although his school was still located in the city.
To counter the boredom during the long drive, Miller's mother gave him albums to listen during the commute, including David Bowie, Elton John and Fleetwood Mac, which sparked his interest in music.
"Ziggy Stardust, Elton John’s Greatest Hits, and Rumours by Fleetwood Mac, so I just listened to those non-stop, back and forth, all the time.
He also spent his weekends playing piano at places such as Rockwood Music Hall, The Bitter End,[4] and the burlesque bar, Slipper Room in the East Village.
[2][3][5] Miller was signed to the independent label, Glassnote Records in early 2014[6][7] and subsequently dropped out from NYU due to scheduling problems (especially since he played music in a number of NYC venues).
