Lagrimas y Sonrisas by Rodolfo Biági. Check out the micro-musicality in this great video.
Our favorite interpretation of Milonga Para Una Armonica by Victor Hugo Díaz. The music in this interpretation is actually performed by Beltango. Once again, Chicho and Juana blow us away with their musicality, subtleness, and interesting interpretations.
Lazzarella by Domenico Modugno. Not a traditional milonga but definitely something fun.
