youtube.com/watch?v=zeq4_eRWF1A The Vienna Improvisers Orchestra is focusing upon conducted instant composition: a piece of music, spontaneously developed by an improvising ensemble and an improvising conductor using hand-signs for structuring the music given by the ensemble. Within an oscillating dialogical process between musicians and conductor the musicians are asked to interprete the given hand-signs by the conductor who rereacts to the music created by the ensemble by transmitting the spontanous creation, an ad hoc composition. The Vienna Improvisers Orchestra is Austria's first orchestra dedicated to this method which has been developed in variety by a few European improvising orchestras within the last 20 years, manly referring to Lawrence D. Performing in ever changing line-ups, the Vienna Improvisers Orchestra unifies singers and musicians from all musical fields out of acoustic and electro-acoustic improvised music, contemporary composed music, jazz and others, among them members of eminent Austrian ensembles such as Tonkünstler NÖ, Klangforum Wien, Ensemble Reconsil or ensemble xx. Since its beginning, the possible processes of merging sound and recitation, their vice versa influence, the metamorphosis of sound- and word-pictures a. phenomenons arising, were an additional beam of VIO's poetic presence, hence the VIO is collaborating with splendid writers in experimental poetry such as Gerhard Rühm (*1930, founding member of the Wiener Gruppe), Gerhard Jaschke, Magdalena Knapp-Menzel, Peter Waugh, Petra Ganglbauer, Margret Kreidl, Semier Insayif, Ferdinand Schmatz, Peter Pessl, Dieter Sperl, Sophie Reyer, Ilse Kilic, Fritz Widhalm and others.
‚Zur Morphologie der Plötzlichlichkeit’, 'ich spreche nicht : illusionsgebiet nervenruh', 'Explosive Litaneien', ‚einklang mitsprache’ and other titels were programmatic routes for VIO's ad hoc composed constructions of meaning. The Vienna Improvisers Orchestra works within different contexts not only with authors, but f.i. with the Budapest Improvisers Orchestra, GGRIL (Canada), Josefa Alonso (Madrid), choirs, non-local musicians or live-scoring the classic russion futuristic movie AELITA (1924) collaborating with institutions and partners such as KulturKontaktAustria, EU/SohoInOttakring (project MELT), Artacts Festival St.Johann, SeeLab, Brunnenpassage, Reaktor a.o.,
performing at Künstlerhaus Wien, festival Wien Modern, Porgy & Bess, 21er-Haus/New Museum of Contemporary Art, Art Brut Center Gugging, ZOOM! festival/Jazzwerkstatt Wien, RadioKulturhaus Wien, Harom Hollo Budapest, Offenes Haus Oberwart a.o. The VIO's music was air-played on ORF/Austrian broadcasting station Ö1 ZeitTon and Jazznacht. The Vienna Improvisers Orchestra was launched by Michael Fischer in 2004.

The VIO, July 11 2026 at the Semmelweisklinik, Vienna
Many thanks to the SWK team!
Dear audience, what a delight it was to have you here and to witness your joy!
As we keep receiving lots of enquiries about audio and video recordings of concerts: yes, they do exist! We’re working on releasing video recordings of this concert, but it will take a little while yet. - In August, we’ll also be recording studio concerts with two different ensembles as part of the RKH Summerstudios, thanks to funding from the SKE Fund, with a view to releasing them.
You can also purchase the LP of our enthusiastically received concert at the Moers Festival 2022 right now - just email us at [email protected].
You might also be interested to know that donations help us to support our work on releases by overcoming financial hurdles and speeding up the release process! You can find out how to donate on our website viennaimprovisersorchestra.org (see 'support').

In this year's second collaboration between the University of Music and Performing Arts Vienna (MDW) and the Vienna Improvisers Orchestra, the Vienna Improvisers Orchestra Prize was once again awarded as part of the Leonard Bernstein Institute competition. - This year, the prize was awarded to two winners: Jakub Piaskowski will be performing at our concert this coming Saturday, and we look forward to welcoming the second winner, Ema Sunjic, at one of our upcoming concerts.
The collaboration and the wonderful initiative to award the Vienna Improvisers Orchestra Prize stem from an idea by Maria Gstättner (MDW), who has thereby made it possible to pass on a specific expertise in a particular area of improvisation to young students!

This Thursday, the VIO will unfold its radically ad hoc-created music within and in harmony with the acoustics of the 8-metre-high hall at the centre for arts and culture Semmelweisklinik, - a venue of great beauty in many respects.
As is costumary at VIO concerts, new musicians will be joining the line-up which is always curated and constantly evolving. - This time, Manuel Schager and Daniel Bierdümpfl will be first time participants. John Edwards (London based, in Vienna on a short concert trip) and Nikola Vukovits will be playing for the second time, and Georg Schmelzer-Ziringer will be joining us again after a long absence – not on the bass, but on the violin.

We’ll also be bringing a few copies of our vinyl album from our concert at the Moers Festival: “VIENNA IMPROVISERS ORCHESTRA live at moers festival 2022”!

This coming Friday, you are cordially invited to enjoy the Vienna Improvisers Orchestra concert, which also means letting yourself be energized by the VIO's unique atmosphere during and after the concerts, and, if you like, purchasing the VIO LP, which features the entire Moers concert.

After concerts in November at the Music Unlimited festival and the Wien Modern festival, we continue with a (second) collaboration with the Brno (CZ) ensemble for contemporary and improvised music Dust In The Groove, which, under the direction of Radim Hanousek, operates at the intersection of experimental jazz and contemporary music.
Look forward to absolutely and exlusively ad hoc created music pieces in the acoustically well-adapted premises of the Westbahnstudios in Vienna!
