Piana's earlier work helped me through some really rough times. And she follows me on Twitter! make sure you listen to Something Is Lost on her first album!
Yuka Kitamura (known for her work on Dark Souls, Bloodborne and Sekiro, she's is one of my great inspirations) and Alex Roe (one of the best known Dark Souls fan music composers) worked on it.
Ed Harrisons Neotokyo OST is an incredible work of art. So far ahead of its time that it feels like wizardry to me. Make sure you check out Departure, Annul, and Tin Soldiers.
