The imaginary game for this imaginary OST is called Irish Goodbye, a surreal narrative-driven walking simulator where a man is lulled into a primeval forest to defeat and assimilate 3 different symbols of his inner self: a creature of malice and violence, a woman of terrible and destructive beauty, and finally, a child that can never grow old.
The melodies generally represent the themes of setting off on adventure (Tavern Bardsong), being enraptured with the initial thrill of the unknown (Liminal Spring), a transition into meditative and transformative sadness after encountering the destructive and magical brutality of the forest (Irish Goodbye Epilogue), and finally a song of triumph as the man emerges out of the primeval forest as a fully integrated whole (Light of Hope)
I think this playlist would benefit from more melancholy melodies / sad themes to convey more struggle throughout this imaginary narrative, but this is a taste of an idea that could be.
I hope you enjoy!
