Edith's guest on the latest episode of Soundtracking is a composer who has been pushing sonic boundaries for three decades. As well as releasing numerous albums and EPs under various monikers, Matthew Herbert has also scored a diverse range of films, including three for Chilean director Sebastian Lelio. The word is overused, but we reckon he's a true visionary. He now has television credits to his name too, with his latest project Temple currently available on Sky and Now TV.  As always, you'll hear plenty of Matthew's work throughout the conversation.
