Improvisation group looking for instrumentalists

We’re a group (piano, tenor sax, bass, and drums) meeting about once or twice a month in Weißensee to improvise. We usually start playing without much planning, and tend to lean more toward groove‑based improvisation rather than completely free. Sometimes someone brings an idea or a jazz standard to explore.
If you play your instrument at a good level and feel you could complement the group, feel free to reach out!
