Marcato Sound, who made pony music 7 years ago, just returned to the scene with an OST piece written for the pony fanfic Into the Light... that's he's written! Dual-wielding arts, the musician blows us away with an Epic Orchestral style featuring choirs and guitars! The concept summed up in the description sounds quite lovely and inspiring, too!
I didn't know about this pony musician before and I'm currently going through his channel and listening/saving his past pony songs at the time I'm writing this, awesome stuff!! I recommend it!
