Two years ago, a Welsh folk band, Burum, had travelled to India where they collaborated with three Indian musicians to play in music festivals in Goa, Kolkata and Bengaluru. Burum's repertoire of Welsh traditional music, re-imagined for a modern jazz tune married Indian classical tunes to create a sound hitherto unheard. Khamira means 'to ferment' while Burum means yeast, in Welsh.
