This article is the first of a two-part article on 21c Spanish choral composers. Part 1, here, features six prominent Basque composers: David Azurza, Javier Busto, Josu Elberdin, Junkal Guerrero, Xabier Sarasola and Eva Ugalde. The article was a collaboration between Nuria Fernández Herranz, conductor, Elena González Correcher, singer/author, both in Spain and the ICB’s repertoire editor/conductor Marian Dolan (USA). The article is in both English (p. 1-7) and Spanish (p.8-12), and includes hotlinks to composers websites, score samples and videos, including a full playlist (http://bit.ly/ICBSpain1). The International Choral Bulletin is published by the International Federation for Choral Music (http://icb.ifcm.net/).
