done that, over and over...
Essentially that's what Foldgallery was all about - an artist-curated space, albeit without the studio group. We also had various exhibitions in the space I was in Glasgow previously. Although there's lots of problems with them, and a lot of constant work, I think on balance the good bits outweigh the bad. The best bit is seeing great work everyday by other people - often new people with completely different approaches to your normal practice, or those in the group. as such, they constantly spur you on and help broaden your own ideas. the biggest down side, particularly with studio groups, is the curation itself. Curating by committee is never a good idea and can either lead to bad shows, or bad relationships in the studio. Best to assign curators to each show. Artist-curated spaces are great fun and can be really interesting and fulfilling things to be involved with. Fold's main influence was City Racing in London at the end of the eighties - a squatted betting shop which played a key role in the re-birth of British Contemporary Art - alongside Transmission in Glasgow. Have a word with Art gene crowd too. They're really connected with other artist spaces.
Hope that helps. Always happy to expand any of that - you have my email and phone number anyway.
