I think Helen Razer captured some of their appeal well, when she wrote:
The Kransky Sisters have emerged from an Oedipal nightmare to change the songs of Michael Jackson forever. Looking like pill-addled bank tellers circa 1981 and sounding like a sherry-addled Country Women's Association musical auxiliary, the Kransky Sisters cannot be adequately described in text.
If they were a smell, it would be naphthalene flakes and sausage mince. If they were a flavour, it would be lard, tea-cakes and fear.
Alleged natives of unremarkable Queensland burg, Esk, these girls offer a seamless performance and an entirely new spin on drag. Their views on femininity, pop culture and the nuances of gravy are extraordinary and bust-a-gut, shed-a-tear, sputteringly funny.
The Kranskys' world of doilies, repression and vintage Butterrick patterns gone horribly wrong must be seen to be appreciated. This twisted representation of suburban Australian femininity is up there with Dame Edna - they are that good. Don't even think about missing this show.
I would add that the Kransky's also layer in a whiff of old school Eastern European repression, as if they were first generation immigrant children of slightly mad and fearfull parents from Warsaw, or the Russian Steppes.
On last night's episode of In Siberia Tonight they did a cover version of "Intuition" by Jewel, full of tuba highlights, that gave more than a nod in the direction of a Volga folk song, that had me squealing and rolling on the ground with delight. If they bring their comic cabaret show "We Don't Have Husbands" to Sydney again (because I missed it last time) I'm so there.
