Elegant, serene, new-wave, profoundly tuneful playing, with accompaniment from Abhijit Banerjee’s tabla and Sudipta Remy’s tampura.

Kushal Das is a master of the surbahar, a kind of bass sitar, with long sustain, ideally suited to this profound and elevated, tricky and subtle, darkest-night raga, recorded in concert at the Radio France Auditorium in Paris.
