one entry listing it as "alternative / punkrock". I guess "Transplation" is "Transplantation"? In any case this does have some punk sounds and seems pretty amateurish, which isn't always a bad thing. The Encyclopedia of Swedish Punk says "uneven and dark but may attract 77 [style punk] collectors".
