Returning to Crystal Source is Function C under his Keelin Temple guise with a storming two track EP. First out of the box is Prysm, a massive uplifting number with an enchanting melody, backed by a driving bassline and thumping kickdrum. On the flip side is The Rabbit Hole. A chunky number here with a build that gently teases in some light synths and crunchy acids over a solid bassline before dropping into a gentle breakdown which drops into a twisting synth line.
