SN Variations is pleased to announce its 5th release. Adrian Corker returns after a break living in Warsaw with two tracks composed for Lock Grooves recorded onto acetate, percussion by Sam Wilson (Riot Ensemble/Actress) and violin performed by Aisha Orazbayeva. The tracks also feature the piano of Mark Knoop and the voice of Josephine Stephenson.

A lock groove is one cycle of one groove on a record. This is 1.8 sec cut at 33RPM and 1.33 cut at 45RPM. Having used lock grooves on film scores for British film Waiting for You and The Have Nots directed by Florian Hoffmeister, Corker wanted to explore their potential further in a standalone more percussive release. He used the cutting lathe currently residing in the living room of The Exchange mastering legend Graeme Durham to experiment with different sounds cut onto acetate and then recorded over different durations back into a computer. These are combined forming frames for performances of violin, percussion and piano.
