According to the globe-trotting musicians of Balungan, however, the train à grande vitesse is already at the station. The 13-member band kicks off its debut, Kudu Bisa Kudu, with the nostalgic steam whistle and intentionally garbled boarding call of “Javanese TGV”, but as soon as Franck Testut’s driving bassline gears ups, it’s clear that we’re riding a 21st-century conveyance. Gang vocals, hairpin-curve guitars, and accelerating arpeggios played on tuned percussion also announce that this is a multicultural journey—and in fact the group is made up of seven of Java’s most open-minded gamelan virtuosos, plus six equally adventurous rock musicians from the south of France.
