Nattens Madrigal – Aatte Hymne Til Ulven I Manden (translated as "Madrigal of the Night – Eight Hymns to the Wolf in Man") is the third studio album by Norwegian band Ulver, issued on 3 March 1997 via Century Media.

Composed and arranged during the first half of 1995, Nattens is a concept album about wolves, the night, the moon, and the dark side of mankind.

[1] The third and final album in what has become known as Ulver's “Black Metal Trilogie,”[2] Nattens madrigal marked the band's international debut and showcases an abrasive black metal style similar to the darker, heavier tracks on Bergtatt, abandoning acoustic and atmospheric elements with an intentionally underproduced sound.

Commenting on the rumours surrounding Nattens Madrigal, Rygg said, "Do you really think that Century Media advanced us so much that we could buy a black Corvette?

It got into the mainstream and people became very adept at playing and producing professional records, and as a result of that it lost a lot of the magic that it held to me when I was a teenager listening to old Celtic Frost rehearsals, or old Mayhem demos.

"[9] Writing for AllMusic, Steve Huey argues that the essence of the album is its "sheer sonic force",[4] which John Chedsey, writing for Satan Stole My Teddybear, finds unpleasant, remarking, however, that the songwriting is an inventive "tour de force" of extreme black metal.

[13] Deathmetal.org, to the contrary, says that although Nattens Madrigal boasts "an enticingly slick take" on black metal aesthetics, they label the album "a classic Darkthrone ripoff" attempting to make a competent but unoriginal product accepted by the mainstream, noting its kinship to preceding styles of popular music.
