In this video, Norwegian violinist Henning Kraggerud amd jazz pianist Bugge Wesseltoft perform an inprovisation on a folk tune.

Kraggerud is playing his custom-made ‘viola concorda’. ‘I was longing for a sound that I couldn’t produce, so I ordered a new instrument from Ariane Becker,’ he writes.

‘Listen to our invention: the six-string viola concorda in an improvisation with Bugge Wesseltoft, on a tune collected by Kirsten Bråten Berg. It has also been recorded on the CD Last Spring through ACT, but of course it is different every time.’

Kraggerud and Wesseltoft will be playing together at Jazz at the Berlin Philharmonic on 14 November 2018.
