Bruce Russell launched his book Left Handed Blows: Writing on Sound 1993-2009 tonight. It's really, really good - and not just in terms of sound, but culture in general; production, resistance, the possibility of radical action; the understanding of one's position within a semantic economy. There's a lot of material in there that is going to be very helpful to me - I'm writing on improvisation and text at the moment, and one of my intentions (they are various....) is to look more at artistic economies as wholes - media-centred distinctions are counter-productive (as Bruce states in the introduction to the show Towards a Cinema of Pure Means currently at the Physics Room gallery).
I've got a review copy - so a write-up is impending. I highly reccomend it - and anyone who is not familliar with Bruce's work should look into it - here's his Wikipedia page.
