The Carnival in Uruguay covers more than 40 days, generally beginning towards the end of January and running through mid March. Celebrations in Montevideo are the largest. The festival is performed in the European parade style with elements from Bantu and Angolan Benguela cultures imported with slaves in colonial times. The main attractions of Uruguayan Carnival include two colorful parades called Desfile de Carnaval (Carnival Parade) and Desfile de Llamadas (Calls Parade, a candombe-summoning parade).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is summoned by the Desfile de Llamadas parade?
candombe
