with a characteristic rhythmic pattern that could be sung: this is similar to traditional practices elsewhere in Europe (Oral-formulaic composition). So, for example, the first work of literature in Basque ''Linguæ Vasconum Primitiæ'' (1545) by Bernard Etxepare shows long verses that, while deceptively fashioned in metres resembling those used in Romance poetry, follow an internal rhythmic pattern similar to a ''kopla'', so they can be popularly sung. Even today, it is not unusual to see groups of people marching around a town at some local festival singing and asking the neighbours for a food, drink or money donation, while the most famous celebrations following this pattern across the whole Basque Country may be those taking place on Christmas Eve (Olentzero) and the Saint Agatha's Eve (Basque music#Samples), with singers dressing up in traditional costumes. A key figure bridging the old singing tradition of Soule and the folk song revival of the 20th century should be noted here, Pierre Bordazaharre (1907–1979), aka Etxahun Iruri. A xirula player and singer, he collected old songs and fashioned new ones, which eventually caught on and spread, take for instance, ''Agur Xiberoa''. He also contributed to new pastoral (Pastoral (theatre of Soule)) plays in the tradition of Soule, reshaping the pastoral and adding new topics. Meanwhile, new and more urban style musical ensembles and bands sprang up in the 70s, performing first to other's songs of the time at summer local festivities. Yet they gradually developed their own repertoire fashioned in line with the Basque revival and activism (special focus on the lyrics) and ongoing Western musical trends, e.g. folk (Gwendal for one), progressive rock (Pink Floyd,...). As regards choral bands, Mocedades from Bilbao should be highlighted, founded in 1967 initially by Amaya Uranga and two sisters of her. They soon gained public notability by ranking second at the 1973 Eurovision Song Contest. That very year in the same city the prolific Oskorri band (see above) got together featuring folk music, launching first album in 1976, where they paid homage to poet Gabriel Aresti, while in the Northern Basque Country Michel Ducau and Anje Duhalde teamed up and put together the first Basque rock band: The celebrated and politically engagé Errobi, releasing album ''Errobi'' (1975) to critic and public acclaim, ''Bizi bizian'' ensued. The group disbanded (not definitely) in 1979. thumb 310px Rock band Zamara's live performance (Image:Zarama.jpg)Beginning at the mid-60s, Imanol Larzabal led a solo career as a singer songwriter, featuring a deep voice as well as a socially committed and poetic subjects, with the collaboration of domestic and foreign poets and singers. He went through a short period in prison and came back from exile in 1977. Friend of his and son of emigrant Souletin parents, Niko Etxart came back to the Basque Country from Paris with brand-new ideas about music in 1972, so turning into a forerunner of Basque rock music (''Euskal Rock&Roll'' released in 1979) alongside the band Errobi, while especially in the traditional Northern Basque Country some lashed out at his looks, manners and music. He alternately performed onstage in "verbenas" (dancing music in local festivities) with the band Minxoriak up to the late 80s. In the area of Mutriku, Itoiz, a milestone in Basque folk-pop music, was formed in 1978, with Juan Carlos Perez as its lead vocalist and frontman, releasing that very year the critically acclaimed album ''Itoiz'', which contained such poignant tracks as ''Hilzori'', ''Lau teilatu'' etc. Akin ensemble Haizea delivered a couple of good LPs in this period. ), is the Basque dialect (Basque dialects) spoken in Soule, France.
