In 1999, in its 14th edition, the series Jazz of the 21st Century provided an opportunity for jazz musicians coming to Spain for the first time. Artists such as Noa, Gonzalo Rubalcaba, Esperanza Spalding, Thomas Chapin and Esbjörn Svensson have been featured.
The festival inspired Wynton Marsalis to compose Vitoria Suite with the Jazz at Lincoln Center Orchestra and Paco de Lucía as guest. In 2010, it was presented as a CD, as a tribute to Vitoria-Gasteiz and its festival.
The festival is the only Spanish festival that belongs to the IJFO (International Jazz Festival Organization).
