The above video was made on the Glasgow-leg of the recent Cuban Anarchism Reborn speaking tour. Mario is part of Taller Libertario Alfredo Lopez (TLAL) from Havana. You can keep relatively up to date with their activities on their blog (in Spanish).
The group are also fund-raising so as to buy somewhere that could house a permanent Social Centre in Havana. To help them out go to https://www.gofundme.com/gg2wrcac where you can also scroll down the page for an English translation of the project goals.
