I have just returned from the Heart 'n Soul AGM at the Albany in Deptford http://www.heartnsoul.co.uk/. Heart 'n Soul are a leading arts organisation in the field of learning disability arts. They organise fantastic night clubs, provide training and promote and support the artists they work with to develop, perform and tour. Many of their artists performed at the AGM and I particularly loved The Fish Policy: ://www.heartnsoul.co.uk/art_fishpolice.html. I would be really keen to see a project like this built up in South West London, to give the learning disabled artists there the chance to take ownership of their own practices.
The Albany is the base for a range of resident arts organisations, including Apples and Snakes and Entelechy Arts, and is a hub for both arts participation and performance in South East London, definitely worth a visit.
