I thought some people might be interested here in this over-cranky write up for tonight's Hemophiliac appearance in San Francisco. ----------------------------------------------------- Bad blood It must be a source of endless frustration for the starving artists of the noise and free-improvisation scenes, who often have trouble moving a few hundred units of their latest proud creation, to see an all-star side project like John Zorn, Mike Patton, and Ikue Mori's Hemophiliac effortlessly sell out a few thousand copies of an Internet-only CD priced at 45 bucks no less. The real knee-slapper is this overpriced CD (self-titled, and released in 2002 through Zorn's label, Tzadik) isn't even any good it sounds like something you'd yawn and fidget through on improv night at the local art-gallery storefront. So why would anyone recommend seeing this trio live? Morbid curiosity? A celebrities-at-their-worst-style fascination with public failure? Or the slim hope these talented cult icons reach beyond the Knitting Factory improv clichés and smarmy laptop computer gimmicks that characterize so much of the CD? Cross your fingers. 8 p.m., Slim's, 333 Folsom, S.F. $20. (415) 255-0333. (Will York) -------------------------------------
