Night Song is a collaborative studio album by Pakistani qawwali singer Nusrat Fateh Ali Khan and Canadian ambient musician, guitarist and producer Michael Brook.

Khan recorded improvisations for the album, and Brook had to decide which sections, some of which were an hour long, were the best and how they were going to fit together, without having a structural point of reference to start with or aim towards.

"[16] He worked in a method which saw Khan record vocal improvisations onto multitrack tapes which Brook would subsequently add to and layer, part by part, in the style of remixing; unlike the typical method of remixers building their mixes out of recorded parts that had already been carefully selected and edited by the original artist, for Night Song, Brook had to decide which sections out of Khan's improvisations, some of which were an hour long, were the best and how they were going to fit together, without having a structural point of reference to start with or aim towards.

Working with this montage-type approach meant that everything took forever.” However, because Brook had to "do everything" with the S770 sampler, and did not have a hard disk editor available, it was a "made even slower.

"[16] In order to hear whether something worked or not, he had had to load it into the S770 sampler, copy it onto tape, "maybe do this for five or six tracks more" and then create the rough DAT mix to listen to the result.

"[16] Night Song is considered a world fusion album that combines Nusrat's Qawwali vocals with Brook’s electronic ambient music.

"[1] The opening song "My Heart, My Life" features West African kora and electronic backing, with Nusrat singing in a relaxed mid-range voice.

[8] Eyre said that "My Comfort Remains" and "Crest" are "essentially pop numbers with catchy melodies, the former bouncy but static, the latter building towards a revelatory crescendo.

"[8] The fifth track, "Longing", features Nusrat's signature scat singing and his singular wail, "unmistakable even when lavished with effects.

"[8] Consumable Online said that the song is "a slow ballad beginning with a slide guitar's sweet melody and ending with strangled pleas (In English, "my dear longing for you is killing me.

")"[1] "Sweet Pain" begins "deep in dream space with a wandering bassline and a simple backbeat, and then heating up to powerful close with Nusrat delivering spitfire scat.

"[8] "Lament" is "plodding, desolate and dark," with Nusrat droning "without you there is gloominess–come back home sweetheart" as mellow background guitar sounds "soar.

Banning Eyre of AllMusic stated that “wherever you stand on Real World's arty aesthetics, you have to admire the Qawwali star's sense of adventure here.”[8] Consumable Online said that “Night Song makes a great companion to either sudden revelation or a simple evening in the forest, under the stars,” commenting that "it is certainly one of the best collaborative albums of the year.

"[1] The Guardian said it was “a quite sensational slow-burner of an album...Nusrat’s incredible vocal control and gift for wending his way round an evocative melody is bolstered by Brook’s sensitive ambient, gently beat-based arrangements.

"[19] Billboard called it “an album for the ages, solidifying Khan’s stature as one of the world’s pre-eminent singers.”[3] Time Out said “the world’s best singer has a gag put in his mouth and delivers an ambient album that couldn’t be smoother if it was silk.”[3] The Daily Telegraph said that "this collaboration with Michael Brook and his guitars provides the most natural complement to Nusrat's harmonium-tabla drums formula, yet never overshadows the mystical power of his voice,"[22] whilst Folk Roots said that "this is a truly great record.

This is a truly great record,"[3] and The Los Angeles View said that "this collaboration demonstrates a distinct stroke of genius, a most intoxicating spiritually uplifting cross-cultural expression.

"[31] The label said that, "as the name suggests, it's a programme of reissues that brings some of the key Real World releases back into the sunlight as many titles have been unavailable for a number of years.
