Letters, released as a single on 14 May on Hardy's own Ffin Records, is a reworking of On Safari from his orchestral suite Blue Letters From Tanganyika.

Commissioned, premièred and recorded by BBC NOW, Blue Letters was released in 2009 to much acclaim in the specialist classical music press. It was inspired by Hardy's mother's time as a young teacher overseeing mission schools in Africa.

Culprit 1's take on the piece retains the flowing, powerful drive of the original and marries it to a light beat and twisting filters that warp and distort the music to good effect.

He said, "I wanted to stay pretty faithful to the original tune as I liked it so much. I also liked the fact that the music had a personal resonance for John. He used "recordings of people whacking stuff like pipes and doors... samples of classic 808 and 909 machines and a bit of 'mouth percussion' for good measure" in his remix.
