Have music... But how do I find out who made it?

I found a piece of music on the www (Not the full track, really more of a long sample) in poor quality(56 bit Mp3), which is very close to the athmosphere I want in a project.

It appears to be russian in style and with russian speach at the end, but how does one find out what it is and who made it?

Any advice would be appreciated!
