OMG I just love Shanti Shanti! Their music is SOOOO beautiful! I don't know what it is about sanskrit chanting but listening to them singing is just total bliss!!
Totally True Story: They just *spontaneously* started reading / writing / chanting sanskrit before they even turned 10 years old! I swear that's the truth, they're for real!
Here is their main web page.
