In 2024 Jemma and another musician were asked to arrange two compositions (where Jemma wrote the lyrics, melodies, and synth parts) for five selected musicians from The Halle. This was a project led by Low Four Studio and The Halle,  recorded and filmed live and Jemma was the main composer, arranger and scorer. For these two compositions Jemma composed, arranged and scored synths, bass trombone/trombone, bass clarinet/clarinet, cello, violin, vibraphone and timpani.
