I have only recently got round to compiling some of the books I have checked out (and would like to check out) when researching topics for visual music. There are also some great DVDs worth getting. These resources I have compiled into an amazon a store - at present it links to books on the amazon.co.uk website, but I will be also creating a similar one to link to amazon.com
These resources are not all exactly visual music resources, but they are definitely helpful in any kind of visual music investigations or research or in the broader area of audio visual composition/installation/interaction
I have signed up with Amazons affiliate programme, so every link you click from my store and then go onto purchase I get a small percentage. I am slightly monetising my blog to help pay for the time I spend putting work here, so thanks in advance if you purchase from my astore link to amazon programme.
