This is a piece by the cello maestro Giovanni Sollima. The first part actually made me get a litlte misty - and the second is just amazing, in a different way. This man is deeply passionate about the cello, and it comes across in his music, in his performance - it's just amazing.
Here are the urls - embedded video, after the cut.
