States Of Play won Deutscher Jazzpreis – Radio Production of the year for it’s project Sonifikation / WDR3!


The “STATES OF PLAY” ensemble released their second album “SUBSONIC” on April 16. The line-up of the nonet is even more international and orchestral this time around – including Analog Synthesizers and the sound expansion through noise (improvised Foley Art).
The style of the group can be called “Melodic Avantgarde” (press) … – a contemporary, melodic aesthetic with vital roots in jazz – a concept in which composition, team play and open spaces create an ultracreative balance. With STATES OF PLAY, Sebastian Gramss has been pursuing the idea of radical sound morphing as an essential and style-forming component of the ensemble: Various concrete musical situations -> “States” (= sound states) are modified and de-constructed … abstracted and transformed …. and then put together into completely new concrete sound images: “Starting from known, familiar tonal starting points, we move towards an aesthetic expansion and transformation of sound situations – the result is an unheard music flow with fine-tuned emotional and intellectual balance …”


Meteors are the spin-off sextet of the larger STATES OF PLAY ensemble.
New Release – CD & Vinyl – coming out early 2023 (rent a dog)!
It’s a compact sextet line-up:
Shannon Barnett – Trombone / Vocals
Hayden Chisholm /// Wanja Slavin – Sax
Philip Zoubek – Piano / Synth
Christian Lorenzen – Keyboards / Moog / Synth
Sebastian Gramss – Double Bass / Composition
Dominik Mahnig – Drums
Stephan Vester – Klangregie / FX”

Four human and four robotic musicians playing together.

A challenge: What happens when intuition, impulsiveness and emotionality meet algorithms, deep learning and programmed codes?

The HUMAN ROBOTIC ENSEMBLE attempts a dialogue at eye level. The
result is an encounter in which the boundaries between artificial intelligence
and human creativity blur. In which no distinction is made between what is felt, conceived, conceived by humans or analyzed, calculated and calculated by software. An encounter in which the joint audible result is clearly more than the sum of the individual parts.

The live interaction raises questions: How creative can robots be? How quickly do they “understand” and read the resulting musical situations? What can AI mean for our creativity
in the future? And: What does artificial intelligence actually sound like? In the interaction of man and machine, a joint piece of music full of autonomous creativity develops ¬- respectfully, attentively and with subtle depth.

Human Musicians:
Lotte Anker – Soprano Sax.
Nicola L. Hein – Guitar
Sebastian Gramss – Double Bass
Philip Zoubek – Piano

Robotic Musicians:
Helio (Logos Foundation)
Vitello (Logos Foundation)
Tubo (Logos Foundation)

OUT & ABOUT (2018/2019)

In STATES OF PLAY – Out & About, Cologne-based contrabassist Sebastian Gramss unites two congenial rhythm sections and a fine-tuned trio of wind instruments into a unique ensemble in a great act of sonorous synthesis. Orchestral moments á la Ellington and Mingus, Zappa-esque allusions and sonic avant-garde: the essential anatomy of music is broken down to its core elements and repeatedly reassembled in an explosive multiplicity. The result is a multidimensional and shifting music that evolves in an organic flow, continually forming new configurations.

PARKOUR (2019)

PARKOUR is actually a sporty, artistic discipline where athletes, regardless of structural conditions and obstacles, are able to cross a city on a direct route. The bassist and bandleader Sebastian Gramss follows the same principle. He moves across the map through sound routes on which he samples ambient sounds and prepares them as playing material for jazz quintet and music robots. An acoustic site visit, which dissolves from postcard views and road traffic regulations and even opens up new, hidden perspectives on the native city of Cologne.

STATES OF PLAY – Enola (May, 2018)

“The audience is completely blown away by Sebastian Gramss ‘ States of Play, an international line up that emphasizes the discovery character of the festival. Of the nonet only clarinetist Rudi Mahall is known in our parts (relatively), but what a performance we get here. The ensemble is driven by a double rhythm section, which immediately gives the potential of a small nuclear power plant, but it is so much more than that. Gramss ‘ compositions make repeated use of a primitive thrust, which is always accompanied by a compositional ingenuity visit this website, an occasionally staggering stylistic variation and the ability to seamlessly combine the most diverse temperaments and style influences.
[read more=”read more” less=”read less”]The band only comes to rest a few times, but every time it leads to ecstatic reactions of the audience. They are after all treated to an ingenious collage of styles that sounds cinematic and theatrical and then quickly has to give way to thundering fractions, then goes towards electroacoustic improvisation and brass band madness à la X-Legged Sally (do you know them yet?). Exotica, free jazz and passages full of swing, straight from Harlem of the early thirties, are put together, then derailing with a broad smile, end up with a fast big city funk played with so much tension it is on the edge of exploding. It was a tightly conducted and impressively executed opulence and in addition a lesson in colouring outside of the lines that can clearly also impress a large audience.”

Uwe Bräutigam, NRW Jazz.Net
