Folsom Street Parties?

Okay, so it's generally indicative of how well the gay community relates to the rest of San Francisco party culture (or maybe it's the other way around) that LoveFest and Folsom Street Fair wind up on the same weekend. And while my Outlook calendar is so brimming with LoveFest parties for next weekend (mainly on Friday, I guess nobody wants to compete against Seismic at Mighty or the huge hullabaloos at 1015 and the Bill Graham), I've got nothing, nothing for Folsom Street Fair parties. Oh yeah, I know about Real Bad at (urgh) 1015 ($60 - $85, but at least the proceeds benefit LYRIC), and Magnitude ($75 retail, $90 at the door, thank you very much), the Folsom Eve Ball at the Porn Palace (sorry, an event that only has images of women just doesn't appeal to me very much), and Juanita More's Playboy event The Stud (which at least has Safety Scissors as a DJ going for it), but these are all the "official" events - what I want to know is, are there any "underground" parties going on? Any parties with music besides tribal diva house (now that's butch) or stereotypical industrial sounds (how many times will NIN be played this weekend)? Any parties that aren't in megaclubs or mega expensive? C'mon, I haven't had a chance to wear my latex doggie gear out in a really long time, gimme a clue about where I can get my fetish on.
