Umka and Bronevik are simply Rock'n'Roll, Blues, Reggae, Rock and who knows what else band. Starting from kind of sixties rythm and blues (or something like that) to almost everything you can do with guitars, bass, drums, harp and voice. Enumerous concerts, hundreds of songs. At the moment you can find some info about the band and Umka herself at their home site: http://www.umka.ru/english (biography: http://www.umka.ru/english/autobio.html)
