Briefly, I've extracted just over two and a half minutes from my 10 minute version of Long Lankin created for Philip Davenport's The Dark Would exhibition, and added some video. You can see the results below.
The Dark Would exhibition is at Summerhall in Edinburgh 7 December 2013 - 24 January 2014. More details here.
Long Lankin is a traditional ballad (Roud 6, Child 93) here in an arrangement by me, based on arrangements by Martin Carthy and Steeleye Span.
