Hello,

I heard this at a temple in Sri Lanka. Is this a keerthanam? Or is it a Mallari?
Anyone could identify this. (Sorry about the poor clarity and short duration. I could only quickly capture that much)

What is the Raga? Nattai? Gambeera Nattai?

My guess ... Mallari, Gambheeranattai. The first few seconds sound like kalpana swaras.
