For Polish modern music they are kind of "super group" (and that's rare). The band members are:
- Krzysztof Knittel - electronics,
- Jerzy Kornowicz - piano,
- Ryszard Latecki - trumpet, percussion,
- Mieczysław Litwiński - percussion, vocals, other…,
- Tadeusz Sudnik - electrionics,
- Tadeusz Wielecki - double bass.
English bio of Mud Cavaliers is available online if you need it (lacking note about Ryszard Latecki, but he is the one who takes care for YouTube recordings, so check him there).
Musicians of Mud Cavaliers have connections to jazz, ethnic/traditional, classical and other and collaborated (individually) with such authorities as John Cage or Tomasz Stańko. They are also (still individually) Warsaw Autumn festival organizers and preside in Polish Composers Society. All in all, they have a strong influence on Polish culture. Their collective explorations are certainly hard to idiomatize, but may be described as modern/intuitive.
Let's mention one event very fitting to the topic of music games. Mud Cavalliers are known for performing and arranging modern music together with musicians foreign to that field. Their annual "Market for new and used sounds" is kind od a workshop that gathers participants from many different styles of music to perform in an avant-guarde oriented project.
As a personal note, I (odolany) can say from first hand, that this is indeed a nice, "anti-elitist" ;) experience that allows to peek at compositional/arranging process and share ideas or discuss approaches. I had an opportunity of talking over the interactive and playful aspects of music, too. But maybe the best connection to show would be that resulting live pieces are quite often gamey in appearance and performance, especially in conducting aspect:
