Welsh noir series Hinterland (Y Gwyll in Welsh) has been making waves across its homeland, throughout the UK on BBC 4 and internationally on Netflix.
As the second series is launched, composer John Hardy reflects on writing the music for series one:
"The creators and producers of the programme talk about Hinterland as a place that's in their mind and their imagination. It's kind of a fictitious place but you still have to make that, you have to populate it with believable characters and atmospheres to convince an audience. And we try to make music that helps to define what that place is. It's all very inspiring when it is that visually rich, when the pictures are that strong and the sense of lace and mood is that beautiful and that powerful, it really helps to come up with interesting ideas for the sound."
