This is a heavy, near-monstrous release involving Japanese singer and bassis Junko Ueda and the French avant-prog group PoiL.  From their Bandcamp site:

“PoiL Ueda is the result of a collaboration between Junko Ueda, a vocalist and satsuma-biwa player from Japan, and PoiL, a French rock/contemporary music band. The creation is based on the 13th-century Japanese epic tale “Heike-Monogatari.”

The composition is based on traditional epic singing accompanied by the satsuma-biwa and Buddhist Shomyo chant. Through the fusion of an ancient Japanese traditional music with a hyper modern European musical formation, this project offers the opportunity to discover a unique musical universe.

An innovative performance where PoiL’s unrestrained experimental rock blends with the mellow and sinuous voice, the compelling narrative, and the remarkable charisma of Junko Ueda.“
