Celloland’s Mark Summer and Ken Cook held a jazz improvisation workshop for El Sistema students in late October at Club Español de La Plata just outside Buenos Aires. In between each of the three workshops everyone spent time drinking maté and talking about Chacareras and Zambas and Miles Davis and Coltrane, the Blues and learning new words and phrases "como las dicen Los Porteños." Thanks so much to Jonathan Miranda Figueroa and El Sistema of Argentina for making this run so smoothly.
