On Friday, everyone's favourite underdog of an arts centre The Substation turns 21. The celebrations have already started with Sept Fest and peaks with the launch of Several Islands, the semi-fiction book by Ho Rui An about the Sub and the people around it, on Sunday afternoon. Thought I'd join the fun by posting some links to whet your appetite. Former AD Audrey Wong had written a Facebook note in response to last week's Straits Times article on the Substation but she preferred if Substation released it first. But you can also check some thoughts on the arts centre in Ho's blog here and Peter Schoppert's  website here. While we're at it, here's the link to my post last year, when I had talked to the ADs past and present. Do ignore the typos. If you come across any other Substation-related writing floating around online, give a shout and I'll update this post.
