Bob Plant puts out music as Portland Vows, and you should definitely go and listen to his releases on the Concrète Tapes label here and on the Third Kind label here and here.

A list of his published philosophical works can be found on PhilPapers here.

In the episode I mentioned a book by Stella Sandford, Vegetal Sex: Philosophy of Plants which is published by Bloomsbury Press, you can find it here.

I also mentioned Robert Porter's project on 'Philosophy, Theory and the Politics of Everyday Life', you can find out more about it on the Ulster University website here.
