Who knew that Imagine Dragons' "Radioactive" could be mixed with, not one, not two, but THREE songs from the Bollywood movie Dil Se, (1998).
This group, Dhamakapella, does stuff like this all the time, mixing and mashing up popular American and Bollywood songs, and then singing them a cappella. No music; just voices. Crazy, right?
Dhamakapella actually belongs to a larger genre of a cappella, known as South Asian Fusion, which was pioneered by the University of Pennsylvannia's group, Penn Masala. South Asian fusion combines the best of American and Indian music, and the result is aca-awesome.
