Shackle is Anne La Berge on flute and electronics and Robert van Heumen on laptop-instrument. Their aim is to explicitly and subtly exploit shackling in both concept and material.

Shackle and Men with Motors

by Anne on September 4, 2015 in category Shackle

Shackle has had two sweaty and electrifying performances with the electro acoustic duo Maenner mit Motoren in the last few months. Both were at the Kunsthaus Rhenania in Köln, a buzzing building that houses visual and sonic artist workspaces.

The first was on May 12 at the end of a 2 day studio collaboration and the second was on 29 August as part of the Strom IV festival.

Sven Hahne has recently moved to Chili but his wizardly visual programming continues to partner with us!

Both performances were on incredibly hot days in Köln. The audiences sipped beer as we cavorted through musical playgrounds, sometimes spacious and sometimes raucous.

Shackle Affair with Bassoons and more

by Anne on March 28, 2015 in category Shackle

Two American duos will be stopped by Amsterdam and were our guests for a workshop at the Conservatory of Amsterdam and for an evening of composed and improvised music at Splendor Amsterdam.

It was a day of of sonic sophistication that ranged from sheer rawness to sublime beauty.

And lots of bassoon with and without electronics!

The duos were:
Of an implacable subtraction
with bassoonist/composer Dana Jessen and composer/performer Paula Mathussen
Architeuthis Walks on Land
with bassoonist/composer Katherine Young and violist/improviser Amy Cimini



Shackle at ‘a special evening at the Kunstenlab’

by Robert on February 13, 2015 in category Shackle

Shackle performed a concert at the Kunstenlab in Deventer, NL. Invited by Harco Rutgers from esc.rec. Shackle played a 50-minute set presenting their Shackle Bits project.


Martijn Holtslag from VPRO’s 3voor12 also liked it (in Dutch, translation following soon):

“Een verrassende en spannende reis, waarbij twee muzikanten in opperste concentratie aan het werk zijn om de gemaakte signalen te verwerken tot een klankreis die even zacht als snoeihard durft te zijn. Alsof dat niet spannend genoeg is om te zien, of te horen, worden er korte, stille fragmenten uit oude jaren 20-50 films weergegeven, die net te vaag zijn om te snappen waar het over gaat, maar visueel een prachtige aanvulling geven aan de sfeer. Hierbij zijn niet de beelden maar is het klankbeeld lijdend.

Niet voor de meezingers, niet voor de cafésfeer, niet voor een gezellig avondje bandjes kijken, maar wel een prachtige reis waarbij je even tijd nodig hebt om te verwerken wat je eigenlijk hebt meegemaakt en waarbij de klanken even experimenteel zijn als de uitvoering. Kortom: een bijzondere avond in het Kunstenlab.”

The full review can be found here (in Dutch).

Shackle in Canada

by Robert on January 29, 2015 in category Shackle

Shackle is venturing into cover tune territory, taking tracks from popmusic and electronica and Shackling them. We’ve started with Boards of Canada and we’re sniffing around at David Bowie, Son Lux, PJ Harvey and Low and . . . .

Shackle’s new project: Shackle Bits

by Robert on January 29, 2015 in category Shackle

A futuristic city scene from Fritz Lang's 1927 film, Metropolis

With their latest project Shackle Bits, Shackle is including silent film excerpts in their performances as yet another ingredient for improvisation. The excerpts are controlled from the Shackle System and switch most of the time in sync with the musical sections but every now and then have a life of their own. As improvisors we are then faced with the question what will take precedence: sound or image.

Below are some examples of live situations.

A Shackle Affair with Young/Day

by Robert on September 15, 2014 in category Shackle, Shackle Affair

Come see and hear a lively discourse between voices, flutes, turntables, computers, buttons, sliders, pedals and joysticks!

Time: 15:00
Location: Splendor, Amsterdam


The duo Shackle is not only a vehicle for Robert van Heumen (laptop-instrument) and Anne La Berge (flutes, electronics) to explore and discover ways to bring exciting and interactive new music to the public, it is an ongoing project to invite other artists to enter into our intimate way of working. Our guests for this concert are the duo YOUNG/DAY from Los Angeles: Andrea Young (voice-controlled electronics) and Michael Day (prepared turntables). This will be the second Shackle and Young/Day Affair. The first was a romping concert in Los Angeles in April 2014.……
