Yes, these are electronic components. And they’re not to be used by the typical kind of geek you would expect. They are used by a bunch of artists to create their own sound synthesizers.
I think art is more interesting when it is based on some technique. Creation makes more sense when we actually make something.
Manu is an artist in Barcelona. He works in an artist place called the Hangar. There, dozens of artists of all kinds have their own space where they can dedicate to their art. Every Thursday they open their doors to the public, and organize workshops or other kinds of events.
The first floor is dedicated to technical artists like Manu. For his synthetizer, he designs the whole electronic circuit, buys the components and integrates everything to get the sounds he wishes. It is a strange activity where art meets open design. That makes the Hangar a place full of passion, and this is part of what makes Barcelona so creative.
