What I'm listening to today: "Singularity 157", Echovocation
Long but satisfying Space Music saga. Watch carefully at the bottom and you'll see that what sounds like the lead synth is actually a kalimba (simplified Zimbabwean finger harp). You're basically listening to a long kalimba performance fed into a long chain of modular equipment that filters the sounds into aftershocks and echoes far larger than its input. Interplanetary craft approaching space dock.
