Song i heard with violin and cello in it?

i heard this song at my school maybe a week ago. it was a kinda slow song with a violin and a cello in it and a man was singing it. it is prolly new but if it is not it is prolly bout a year old.it was a very deep cello. soooo i kno thats not really a lot of information but if u can just give me as much songs that could be related to this as possible. ALSO it is definitely not rock at all.. he has a softer kind of voice.
