L_ is a short EP, consisting of 3 version of the same work. In 2015, Ryterski was asked to make some music to a short video, directed by Zofia Czerniakowska. He decided to create a very abstract, ambient soundscape, with a lot of glitches and short, but soft sounds. During the process of tweaking the details of the piece, composer created 5 version, each varying a little bit from each other. Finally Ryterski decided to publish the first, third and the fifth version on SoundCloud.
