Have you ever heard of Two Steps from Hell, the American music production company?
I have not.  What kind of music do they produce?  Is it hard rock, or country, or christian music?
I believe quite a bit of it is rock, but they mostly focus on music for movies and trailers.
Have they produced music for any movies I would have heard of?
Oh definitely. Have you seen Harry Potter? They did tracks for soem of those movies.
Ohh yeah!  I love harry Potter.  So it is mostly instrumental Music?
Yes, they've also supplied tracks for X-Men and Pirates of the Caribbean. 
They do a ton of my favorites and I didn't even know it!
