It is not nessesary that two excellent classical musician have to play this music as tango musicians. They are classical musicians and offer a different classical approach to this music which by the way was written originaly for a great classical musician - Rostropovich. In that way we have divercity of musicianship which turns the interpreting of music into real art.
This has plenty of passion and fire but it is a classical kind - the tango shouldn't push forward like Tchaikovsky. The more fierce the rhythms get, the more you have to fight the urge to rush. It's difficult because the body moves differently than classical musicians are trained to move. Juanjo Hermida, Fernando Suarez Paz are perfect examples...the musicians in this video are capable of playing like real tango musicians if they work on it.
