Hello Anne!
I guess I have a few tracks that may suit your needs very well!
First of all, you can try with this one, All Hopes are Gone in the Dark, which is very close to what you are looking for. It has a similar tension and a great rhythm.
You can also try this one, Inspirational Rock. It may work out good for what you looking for.
For similar tracks to the two above, try here, there are more nice ones.
You can also try to listen to this one, Courageous Decision, which may greatly fit what you asked.
Otherwise there is this great track, Epic Violin, which is kinda slow and tense. Give it a listen!
If you need more similar music, or just for future reference, here is my profile, where you can find tracks divided by genre or simply my entire portfolio. Be sure to check it out, we have good quality tracks suitable for a very wide range of situations. Of course all of our tracks are available for extended licence too.
Good luck with your project! Wish you the best.
