Funny you should bring up those two names as both are close friends with each other and with Hogg. That's Sioux dancing with her in the Electric vid.
Hogg has been part of the avant fashion world since the early eighties. She's always in tow with everyone from Bowie(which is most likely where you, Mr. Lion, heard her name
) to Boy George to Sioux to Harry.
She's ALWAYS against the grain of EVERYTHING. Right down to signing a record deal. Negotiations started in the early 90's and here we are still waiting.
