Mikel Laboa Mancisidor was one of the Basque Country's most important singer-songwriters.

Xabier Lete Bergaretxe was a Basque writer, poet, singer and politician. He started to write from an early age and he often published articles in the magazine "Zeruko Argia". In 1965 he created a band of Basque Music with Mikel Laboa, Benito Lertxundi, Joxean Artze, Jose Angel Irigarai and Lourdes Iriondo. The band, which was called "Ez Dok Amairu", disappeared in 1972, but Xabier Lete kept on singing with Lourdes Iriondo, who, by that time, had become his wife.
