This piece is a live performance of Orchestral Tango. The performance contains instruments such as the Bandoneón (accordion), as well as the traditional tango rhythm. It also contains other ensemble elements, such as volin, bass, cello and piano. When listening to this piece most listeners (unless musically trained) would be unlikely to know about the roots of the arrangement, however as ethnomusicologists we can recognize that it actually originates from Argentina. 

Enjoy!
