Hi, nice review, a good read. For your info..
The installation in Hope St. is a sculpture by John King called 'Case Histories' which has been there since 1998 (so nothing to do with Biennial), there are several concrete copies of suitcases, travel bags, guitar cases etc. which belonged to famous people with Liverpool links. So there's the Beatles of course, the Liverpool poets, Charles Dickens, Malcolm Sargent, loads more. The buildings behind are The Art College where Lennon and Stu Sutcliffe studied and next door is LIPA (Liverpool Institute for Performing Arts) which used to be the Institute School were McCartney & Harrison were pupils (as was I).
You were too late to see most of the Independent Area exhibs. The Bloomberg New Contemporaries had been there but finished on 23rd Oct and the building you show should have finished on the the 30th (when you were there I think) but inexplicably closed a day early! Shame because there was a lot of weird and interesting stuff there.
Thanks for the clarification, and the extra info about the buildings behind. That'll be why none of my Biennial related web searches could find it, but that said, I still can't find the article I read about it even now I know the name...
(And comment editing can be done, in a roundabout way, if you ask nicely ;-)
