collaborations with jazz musicians like Matteo Salvatore, Battista Lena, Eugenio Colombo, Natale Galletta and Enrico Rava. Another culturally unique musical tradition in Southern Italy is the zampogna, a form of bagpipe originally played by the shepherd class and is still prevalent in the mountainous regions of Southern Italy and Sicily. The Zampogna, in addition to secular use is associated with the annunciation of Christ and it is still not uncommon to see a zampogna player at a nativity scene during the Christmas season. The zampogna is most likely a direct descendant of the Greek aulos and more similar Roman tibia utricularis. Ethnic Greeks The ethnic Greeks living in Salento (Puglia) and Calabria have their own distinct dialects (Griko and Grecanico, respectively). They have lived in the area for an undetermined amount of time, possibly as early as Ancient Greece or as late as the Middle Ages. The community has been largely assimilated by the Italian nation, but there remain speakers of the dialects and other aspects of the culture. There was a roots revival in the 1970s in this area, paralleling similar developments across continental Europe, including Brittany and Catalonia. Folk musical traditions in the area include a religious piece, Passiuna tu Christù, which recounts the Passion of Christ. The Passion is performed by street accordionists with two singers. An example of a pizzica song from Salento region is Kali Nifta (Good night). The lyrics were written in Griko by Vito Domenico Palumbo (1856–1918). Sicily Sicily is home to a great variety of religious music, including a cappella devotional songs from Montedoro and many brass bands like Banda Ionica, who play songs from a diverse repertoire. Harvest songs and work songs are also indigenous to the agricultural island, known as "Italy's granary". Franco Battiato, Fratelli Mancuso, Luciano Maio, Taberna Mylaensis and Ciccio Busacca are among the most popular musicians from Sicily. Busacca has worked with Dario Fo, like many Italian musicians, but is perhaps best known for his setting the poems of Ignazio Buttitta, a Sicilian language poet. Fratelli Mancuso (brothers Enzo and Lorenzo Mancuso) have fused traditional Sicilian peasant songs (), monodic chants () and other indigenous forms to create a uniquely Sicilian modern song style. Sardinia Probably the most culturally distinct of all the regions in Italy, Sardinia is a Mediterranean island known for the cantu a tenore polyphonic chant, sacred songs called gozos, and launeddas, a woodwind
