Kolkata-based musician Nilotpal Das aka Bios Contrast's new album 'Red River', arrives as a narrative sequel to his 'Dragon Rising' LP on Hong Kong DIY label Mouhoi. The concept behind the record is a speculative historical drama and myth taking place during the deadly Kalinga War in the Mauryan Empire of India.

Following his intensive 24-hour harmonium drone compositions, Das's 'Red River' uses recordings of Bell 407, a civil utility helicopter as the main body of the record together with a 47-year-old harmonium, field recordings at Chandraketugarh, custom built woodwind prototype instruments together with guitar, violin & vocal improvisations.
