The origins of “Legend of the Lake” lie in music Gareth Glyn composed for a film which wove a tale of smuggling, treachery and unrequited love into the fabric of old legends - some dating from Celtic times - about one of the many sacred lakes of Anglesey. Whether the music depicts the fleet-footedness of smugglers’ ponies, the summary punishment of outlaws or the bittersweetness of remembrance, the theme of the Spirit of the Lake, first heard on a distant trumpet at the beginning, is never far away.
