Illya Kuryaki and the Valderamas return with Leche, another example of the Argentine group’s fusion of rap and rock. Their psychedelic side emerges on tracks like “DJ Droga” and “Apocalipsis Wow!” while “Latin Geisha,” “Robot,” and “Guerrilla Sexual” demonstrate the fluidity of their rapping. Leche is another diverse and entertaining release from one of Argentina’s most inventive bands. – Heather Phares
