While carrying out my research as a little refresher into what inspired and contributed to both modernism and post-modernism I came across this really useful Youtube channel called "Little Art Talks". If you want a quick brief reminder on a certain art topic such as colour theory or a movement such as Dada then this channel is for you. I find the videos to be short, concise and have useful keywords and Karin Yuen who produces the videos mentions key artist and designers, which can then lead you onto further research and insight into the movements.
Please see the link below if you too would like to view her videos.
