This is a fun work that was conceived as an "Encore" piece. 
This short piece its a waltz for double bass alone but the performer should act like is very drunk while playing, so the waltz gets a bit transformed into a very complex and virtuoso work. 
This was a comission by 2017 Montevideo Bass Festival, and was the required work for the international solo competition. 
It was also the required work for the Galicia Graves (spain) International Solo Double Bass Competition, in 2018
