Asia is a huge continent, and these folk and classical pieces span countries, languages, and even tonal systems. If you’re not attuned to the nuances of Indian raga, it still makes for pleasant listening, a soothing river of resonance; if you are, the escalating micro-tweaks to the central motif and intricate meshing of sitar and tabla can be downright magical. Operatic Chinese classical compositions like “The Small Murmuring River” are overwhelming in the best way, and the melismatic Sufi chants of Abida Parveen and Rahat Fateh Ali Khan will move you to tears.
