Hans A. Lang has been playing the hurdy-gurdy and diatonic accordion (hand harmonica) since around 1985. Several of his own compositions were created in the group ''Trio Grande'' which can also be found on LP/CD and, for some time now, on Bandcamp: https://triogrande1.bandcamp.com/
The appeal of writing pieces for the Bordun instrument hurdy-gurdy lies in allowing the Bordun to be somewhat “forgotten” through the possible two-part harmony and harmonization. At the same time, this music always moves between tension (tones foreign to the Bordun) and resolution (matching the Bordun).
