What is the song that plays in Naruto Shippuden when Deidara fights Gaara?


I've been searching for that song for a _really_ long time but I can't find
it. It's kinda sad (?? for me at least) and it has a violin or cello or
something like that.




I think the track is actually called "Stalemate"

It's called Deidara's theme. <https://www.youtube.com/watch?v=0Kd4mOSrTh8>

At 0:42, the strings start playing.
