I come from the generation who were taught never to throw things out. I like the idea of hanging on to things and repairing items rather than discarding them. It’s not a question of money, more to do with guarding resources and not being wasteful. My children laugh at me when I sit darning a pair of socks.

Occasionally there would be something I didn’t recognise and I’d record it with a question mark or, as a joke, LGM for Little Green Men. It was easier than saying “you know that funny pulsing source at right ascension 1919, declination plus 20”. So, it became LGM.

And what happens for me is that I make a pot of beans on Sunday. And I also make some greens with chard, whatever I have available. And when I come to cook a meal or even to make myself breakfast, I may warm up some of those beans. I put a little tortilla right on the fire. I fill it up with the beans, maybe a little hot pepper, and I eat it. And that takes me exactly two minutes, three minutes, maybe. But it’s knowing how to cook. Those basic things have been taken away from us.

I then converted a bathroom, seldom used by the family, into a laboratory and spent hours playing with chemistry sets. With the help of an aunt, Esther Molina, who was a chemist, I continued with more challenging experiments along the lines of those carried out by freshman chemistry students in college.

It’s wasting time to listen to music when you go outside because there are so many interesting noises. For example, every time it rains, I open the window and put the recorder outside. I should always be ready to be surprised, like by the siren of a patrol car in Barcelona and other cities. I hit things, on the street or anywhere, to check the sound—until I find the perfect idea of sound. I haven’t found it yet and am always searching.

I guess it’s by some degree of my own satisfaction. It’s not numeric. For instance, I’m very proud of async , but in the 90s, I was making fake R&B, fake House music, and fake Hip-Hop music. I don’t like that. I’m not happy about it. I wish I could erase that time. Making film music is different. It’s for other people, not yourself. It is still my own music, but it’s for other people. My solo work is entirely for myself, so it’s judged by my own satisfaction and whether I have proceeded enough, if I have pushed myself to another level. That’s how I judge it.

You know, I have doubts, but the images, like the movies, always inspire me. So when I’m empty, vacant, I start watching any movie, b-class, c-class, it’s okay. B-class kung fu movies are so inspiring. The music, for kung fu movies, very old kung fu movies, not sophisticated ones, is so inspiring. They’re so wild. I was watching those kung fu movies while I was making async .
