Both the music and the visuals are generated in realtime using the input of two electric instruments (a wind instrument and a piano).

Genesi by Abstract Birds
Genesi (trailer) from Abstract Birds on Vimeo.
This is a very beautiful work and at present one of my favourite audio visual pieces - ok I do have a lot of favourites, its the quietness and simple shadings - just great.
"Abstract birds are Pedro Mari and Natan Sinigaglia, two visual music artists.
Their work combines images with sounds through the use of musical instruments interfaced with generative systems dedicated to audiovisual creation in real time.
The musical aesthetic is rooted both in the tradition of classical music and in the well-established tradition of jazz, drawing in particular from the latter the improvisatory nature of execution, which is crucial in the work of Abstract Birds.
The visual aesthetic is abstract, with a conscious use of shapes and colors, although the dynamics of the audiovisual world take inspiration from the natural world."
