“The appliance that thinks it's a musical instrument” seizes center stage in this rollicking tribute to that most maligned of instruments, the accordion. In 1996 five squeezebox superstars united to form Accordion Tribe, a group devoted to returning their black-sheep instrument to the worldwide recognition it once enjoyed. The tribe's diverse members-New York avant-gardist Guy Klucevsek, who's played with John Zorn, Laurie Anderson, and others; Slovenian punk-rocker Bratko Bibic; the classically influenced Finn Maria Kalaniemi; Otto Lechner, a blind, melancholic German self-taught musician; and crazed Swede Lars Hollmer-wheeze and squeeze their way across Europe during a 2004 tour in search of the past and present of the instrument, visiting the Italian center of accordion production, paying homage to the eight-foot-high “World's Largest Accordion,” and creating new sounds. Accordion Tribe revels in the charms of its underdog instrument, and the talents of the musicians who've pushed it to new heights.
