As the picture shows, Flume hasn't forgotten where he came from, despite having just toured the world and hung out with music heavy-weights Skrillex and Steve Aoki. He still lives at home with his parents, and he claims he was never a ladies man. Cute.
He also knows what he's doing. When he started producing music more seriously, Harley was strategic about the marketing of his music. He thought long and hard about the name he'd choose to represent his music, telling The Canberra Times, "If the Flume thing was ever going to have any success, it was going to be printed on T-shirts and posters and magazines and stuff. So, for me, it was really important to have a word that sounded nice and sounded like the music I was making. And also look nice, from a typography perspective. I love the way the word [Flume] sounds and looks, so it really worked for me".
Fun fact: "Flume" was inspired by the Bon Iver song of the same name.
