How it started
The concept of Super-Sonic Jam was born a few years ago in the basement of Paradiso during Super-Sonic Jazz Festival. In those late-night jam sessions, musicians and visitors came together to play deep into the night - driven by spontaneity, creativity, and pure improvisation.
Since early 2024, Super-Sonic Jam has found its home at Skatecafe, where every edition has sold out in no time. Every now and then, we return to where it all began: Paradiso. Each session is hosted by different collectives and artists who bring their own flavour to the stage. London’s Steam Down, Rotterdam’s BIRD & House of Knowledge, Haarlem’s INI Movement, and Amsterdam’s Els Jam and Higherlife Jam have all brought their energy to the mix.
Keys to a Good Jam
Every jam begins with listening. Before you play a note, take in the groove, the chemistry, and the energy in the room. Let the music guide you rather than rushing in. When everyone listens deeply, the whole session lifts.
The host or house band shapes the flow of the night — they help keep things smooth, open, and welcoming. They’ll signal when the circle is ready for new voices and new ideas. Trust their direction so the whole room can stay connected.
A jam is a shared musical home. Play with awareness: balance your volume, leave air in the music, and give others room to express themselves. Think of it as a spacious conversation where every voice matters and the music breathes because of it.
Take your moment with confidence, enjoy it, and then step back so someone else can shine too. Short, meaningful contributions keep the energy moving and make space for fresh ideas. The magic of a jam comes from passing the flame, not holding onto it.
Not everyone will know every tune - and that’s part of the fun. If the music shifts, move with it. Try a new melody, a different key, a surprising rhythm. Creativity grows when we’re flexible, curious, and ready to explore the unexpected together.
At its heart, Super-Sonic Jam is about joy, expression, and connection. Bring good energy, be present with the people around you, and trust the flow of the moment. When you let go and let the music lead, incredible things happen.

Super-Sonic Jam is an open jam session hosted by Super-Sonic Jazz, where musicians, vocalists, producers, and music lovers come together to play, experiment, and connect. It’s all about spontaneity, creativity, and community.
Absolutely! Just keep in mind that each jam follows a set structure. Every edition features a different house band or collective hosting the session. They kick things off, and the host will announce when the jam is open for everyone to join. Make sure to connect with the host on the night to get involved.
No sign-up is required. You can simply show up and speak to the host when you arrive, or make eye contact with the host or band once the jam has already started. Depending on how busy it is, there may be a list — or everything flows more spontaneously.
Expect the Super-Sonic signature blend: jazz-influenced sounds with touches of soul, hip-hop, broken beat, electronic influences, and pure improvisation. Every session evolves according to the musicians present.
Core backline (drums, keys, bass amp) is usually provided, but we always encourage musicians to bring their own instruments when possible.
All up-to-date details, including ticket info, can be found on the event page in our agenda.
Yes! The jams are just as exciting for non-musicians who want to experience what happens when talented improvisers create something new together.
