Overture was commissioned by the Swedish Electroacoustic Music Studio (EMS) and the Skinskateberg Electronic Music Festival, which in 1995 had its focus on Mexican electroacoustic music. I was asked to compose an opener to be performed at the beginning of each concert. Wondering what could be suitable for the occasion, I thought I'd risk the idea of including some Swedish and Mexican sonic icons that would be recognizable by all listeners. I finally decided for sounds recorded from a Mariachi band and a 1956 Volvo convertible honking, with its unmistakable horn, an archetypal Mexican urban slur.
