Kal is a group of six Romani from Serbia who have risen out of the oppressive environment, combining musical elements of their native culture with contemporary touches like hip beats and ambient textures. Their self-titled debut is a musicologist's dream, a larger-than-life hodgepodge of Eastern European tangos and American rap with Middle Eastern trimmings. Sung mostly in Serbo-Croatian by front man Dragan Ristic, songs like "Obrenovac Boogie" and "Midnight Walk" are hyper-charged polkas that would go well with Brave Combo or Gogol Bordello. Rarely do cultural significance, top-notch playing and sheer escapist pleasure merge as gracefully.
