Chema Alvargonzález was a photographer and multimedia artist with a sound conceptual style who researches different urban and architectural spaces in which chance is the catalyst for constant transformations. His artistic universe is the object of multiple perspectives and confrontations of concepts: human collective, city, travel, memory, absence and playing with light. He created installations in which light and words written with neon make a pictorial representation on the façades of such emblematic buildings as the Spanish embassy in Berlin (1992), the old control tower at Munich airport (2000) and the Swiss embassy in Berlin (2001).
