Authentic Sri Lankan music recordings to bring home where to actually buy them

Beautiful question because Sri Lankan music is criminally underexported. For physical media, the surviving serious record shops are concentrated in Kandy and Colombo: Torana Music in Colombo 7 (the longest-running serious music shop, classical, folk, Kandyan drumming, full catalog of W D Amaradeva, Pandit Amaradeva and Nanda Malini), Tarana in Kandy (similar but smaller, often has live-recording cassettes from temple festivals), and the Sri Lanka Broadcasting Corporation gift shop in Colombo (official-archive recordings of state-broadcast performances). For Kandyan drumming and dance specifically, look for "Berava" tradition recordings featuring the Chitrasena Dance Company. For DIGITAL: Spotify and Apple Music now have decent catalogs but lots is still missing; YouTube has astonishingly complete archives of older performances; Bandcamp hosts a small but growing set of contemporary Sri Lankan electronica and folk-fusion artists (search "Sri Lanka" or "Colombo"). Avoid the airport "Sri Lanka greatest hits" compilations - hopelessly tourist-curated.
