I suggest you watch YouTube videos. I just tried to find videos on the person you mentioned and am not exactly sure what I was listening to in the videos I found, so I can really figure out what type of music you would like. I could not figure it out. One of her bios said she is classically trained, but what I saw and heard did not appear to be classical. 

If it is classical, Google “classical cello” maybe even select “videos” to weed out non-videos. There are a couple of guys who have cello videos, I think think they call themselves, “2Cellos”. They do a variety of music.

You can also Google a particular style of cello, specific songs, or just “cello videos”. There are CD or MP3 offerings on Amazon and many have partial tracks you can listen to. I used to have a “wish list” for cello music CD’s on my Amazon account page, but I deleted it. I kept putting too many on it and it was too hard to sort. I just search Amazon Cello CD’s now when I am looking.

I am sorry I could not figure out exactly what you were looking for from the couple of videos I tried to watch of Hildur (Gave trying to type the last name properly, LOL. I need an old fashioned typewriter in order to type accurately.) The videos were not classical, pop, or anything I listen to. Maybe you could post a link(s) of a video(s) of hers that shows what you are looking for? I am assuming, she, like many, play many genres. 

Hope this helps.
