Hugh has been involved in many collaborative projects with other artists in the region and outside.
For instance he wrote the words for the song cycle ‘Tidemarks’ about the River Nith in collaboration with composer Suzanne Parry John.
He also wrote a verse libretto for an opera based on the story of Jekyll and Hyde, in collaboration with the New Zealand born composer Derek Williams. Most recently he and the artist Hugh Bryden devised and facilitated the successful ‘Forgotten Doors’ project in Dumfries. Hugh Bryden and he co-host occasional book making and writing courses, most recently at the Scottish Poetry Library in October 2017.
In 2018 Hugh McMillan began a collaboration with the French based artist Robert Campbell Henderson entitled ‘Elspeth Buchan and the Blash o God’, which exhibited in Le Tremouille, France, Thomas Tosh, Thornhill, The Wigtown Book Festival, The Stove, Dumfries and the Scottish Poetry Library from June – December 2019. More events are planned for 2020. In December 2019 and the beginning of January 2020 ‘The Conversation of Sheep’ was used as the inspiration and focus for a series of concerts in Dumfries and Galloway with the Cairn Chorus.
