There's a music theme in I'm Not A Sick Boy and without selling away the story too much, frequency plays an important role.
I never used Spotify before and just tossed in some songs I jam while working on the series (forgive the poor flow of the playlist) lol
The song Joy by Slowdive is a major influence on the two brother MCs and inspired Episode 4 (1b) couldn't find it on Spotify. Gneres like Shoegaze, Indie-Rock, Alt-Metal and Darkwave are my usual go to music.
It's a story where the heroes suffer a condition that transforms others nearby into monsters (unwillingly) creates high tensions and the heroes are their own worst enemy. Death looms and there is mystery involved with the brother's condition. The brothers make it a duty to protect survivors and have to compete with malicious individuals who spin the situation into a game. But with all that the MC brothers are able to revive that close kinship they once shared.
Was also inspired by indie horror and found footage films. As Evan (the big bro) is the face character for season 1, his musical tastes are more prevalent, but as other supporting characters show up there will be other musical genre influences as well. The younger brother, Owen draws influences from 80's rock, new-wave and pop.
Usually jam this for serene moments:
Love and inspired by this QOTSA album animation too
