This pop / rock backing track is written in the key of e minor. So, as almost always in that case, you can use the e minor pentatonic. Of course e natural minor also works fine.
This version contains no bass, there is a link to the full version of this song at the beginning of this video.
I hope you enjoy this one. Check out my other tracks and visit me on Instagram for some guitar vids.
