Pablo de Sarasate - Caprice Basque op. 24 - performed by Itzhak Perlman

A fantastic piece for violin and piano. One of my favourite virtuosic pieces due to the varying themes and challenging techniques.
Here's one of the best performances of this piece done by Perlman done on a backdrop of Basque images. The song ends at ~6:15 -- windows movie maker extended the last picture for some odd reason.
