Immersion's packaging is Spartan or, if that's the way your tastes tend, minimalist. Its music, though, oozes sumptuousness – it's unbelievably well-performed and blissfully nocturnal. Alam Khan is the son of Ustad Ali Akbar Khan. He was a musician of such consummate power, concentrated inventiveness and improvisatory wonderment that Yehudi Menuhin called him “an absolute genius… perhaps the greatest musician in the world”. (And, yes, I doublechecked with Maestro Menuhin). His grandfather was Ustad Allauddin Khan, the teacher of such genre-breaking virtuosi as his son and his son-in-law Pandit Ravi Shankar. (‘Ustad’ denotes a Muslim teacher-maestro and ‘Pandit’ a Hindu one.) Meaning, mighty big shoes for Alam-e-Aftabuddin Khan, born in 1982, to step into. The opening composition in this night sequence is a three-part ‘Kausi Kanhra’, a rare night-time raga that Ravi Shankar demonstrated so brilliantly on his 1991 Maestro's Choice Series One. ‘Kausi Kanhra’ carries the waft of night jasmine and is unbearably romantic. Next is a raga (in two stages) long in his father's repertoire called ‘Durgeswari’, before he concludes with a light touch with ‘Pilu’ as a ragamala ‘garland’ bouquet. I crossed continents to see his father: I would cross continents to see Alam Khan. Immersion reveals his deftness of touch and mind better than anything I’ve heard from him.
