Edging between background ambience and melodic progression, this short, live performance by Alex Roldan is exactly the sort of video that led me to start [my ongoing YouTube playlist of live performances of ambient music](https://www.youtube.com/playlist?list=PLAgCxRbmR1MJxihgJkCPEnehAPvjoF71-). In it, in full view, we watch as Roldan plays a collection of instruments: a controller in the form of that grid, and a trio of sound sources and manipulators. The correlations between audio and physical actions are self-evident, taking a bit of the mystery out of the music, and the processes and tools that enabled its real-time production.
