In March 2017, the outstanding Swiss jazz quintet "Luca Sisera Roofer" played on a tour of Russia with Moscow's famous alto saxophonist Alexey Kruglov as their guest. The music that emerged on stage each evening was magical. So magical that they promptly decided to disappear into a Moscow sound studio between two concert evenings, in order to capture this magic in a recording. Here, the six musicians did not focus on composed material, but on the essence &emdash; pure, free improvisation. The result of this studio session is an impressive musical journey now under the name of Moscow Files, released on CD by Leo Records.
