Jason Heath's post pointed me to learn about the German double bass ensemble Bassiona Amorosa.
All members of this ensemble playing in variable settings are students of the Contrabass Master Class of Prof. Klaus Trumpf at the State University of Music in Munich; all are for the most part multiple prize winners in international competitions (in Germany, USA, CR, ARDCompetition etc.).

In the You-Tube video above, this ensemble performs Sabre Dance.
