Open Sound Spaces: Hammer +3 Brings Jazz into Motion
On November 14, 2026, guitarist Christian Hammer from Gelsenkirchen invites you to a special edition of his concert series Hammer +3 at the werkstatt. Together with Oliver Schroer on piano, Patric Siewert on fretless bass, and Carlotta Ribbe on vibraphone, a concert emerges that blends jazz, improvised music, and contemporary chamber music.
When Piano, Fretless Bass, and Vibraphone Breathe Together
The acoustic piano opens harmonic spaces, while the melodically agile fretless bass sketches melodic lines. Carlotta Ribbe's vibraphone adds resonance, color, and a floating afterglow. Christian Hammer's guitar expands this soundscape with another dialogical voice.
Composition as an Invitation to Improvisation
The original compositions serve not as a rigid structure but as an open architecture. Melodic fragments, pauses, rhythmic shifts, and freely developed transitions engage in an immediate dialogue. The interplay thrives on listening, reacting, and evolving—musical synchronization emerges in the moment.
Four Strong Voices, One Breathing Sound
Oliver Schroer combines a wide-ranging musical practice from jazz, classical, improvisation, and world music. Patric Siewert is recognized as a versatile live and studio musician, lecturer, and award winner in international competitions. Vibraphonist Carlotta Ribbe was awarded the Folkwang Prize in 2025 and won the Women in Jazz – Next Generation competition with the Ribbe/Barthel duo. In 2026, she was also featured as a guest soloist with the WDR Big Band.
Intimate Live Atmosphere with Great Sonic Depth
This concert experience does not rely on grand gestures but on nuances. Fragile, meditative passages can suddenly morph into condensed rhythmic movements. Light, acoustics, and audience mood become part of a stage performance, the tension of which grows from spaces and surprising turns.
Conclusion: Jazz as a Shared Moment
Visitors can expect a lyrical, independent evening with ample space for sound, interaction, and spontaneous development. Those who wish to experience live improvised jazz, contemporary chamber music, and unusual instrumental combinations will find a concert with a special pull at Hammer +3.
