Nights in the woods with LARGO


Only a few more days to see this compact, mysterious piece of musical theatre with the Genetic Choir!

We premiered yesterday and are playing four more nights till Wednesday:

LARGO (Boslab)
a piece by Judith Hazeleger
Music: The Genetic Choir

Start: 21:00

Location: Amsterdamse Bostheater in het Amsterdamse Bos

More info in this previous post
and for tickets/reservations: click here

Genetic Choir in the Woods (Boslab) 10-15 July


LARGO is a visual & musical performance in which time itself is changing pace. We see a group of people approaching. They are coming from the countryside. Slowly, they are coming closer. In what first seemed unity, you start seeing differences. You start zooming in to the smallest detail. LARGO is showing the world in a slower tempo.

10-15 July 2015 – 21:00 in het Amsterdamse Bostheater / Boslab

Tickets: click here

Judith Hazeleger is creating LARGO in het Boslab.

The Genetic Choir is creating the music for it and performing in this  durational physical performance piece.

Come see it!


Amstelpark concerts for Musicians without borders

support_mwb_whiteThis weekend’s Echo: Labyrinth concerts are in support of the great work that Musicians without borders is doing all over the world: Using music to bridge divides, connect communities, and heal the wounds of war.

We are happy to join the initiative of our friends at Splendor who organise a dusk-till-dawn fundraising tomorrow, 21 June: The Splendor Musician Marathon.

Sponsor some minutes of music to support this great cause!

This can be done online here or when you come tomorrow to either the Splendor event in the centre of Amsterdam or our concerts in the Amstelpark: Put something in our hat after the concert to help Musicians without borders continue and extend their great work. We already gathered money for them with our three concerts today, which was a lovely experience with many different types of audience from old to very young. And lovely wheather, too! :-)

Come and help us make an even greater amount for Musicians without borders tomorrow!

It’s a great day to come to the park anyway, as Zone2Source is organising many other things as part of their exhibitions in Amstelpark and the Midsummer Nights Dream Solstice Performances.

Labyrinth_by_snugsomeoneThree more times to enjoy our open-air vocal concert on Sunday, 21st June:

15:00 – 16:15 – 18:00

gathering point: Orangerie, Amstelpark, Amsterdam, NL (click here for Google Maps)

Echo: Labyrinth

a walk and a concert on location by The Genetic Choir, featuring special guest Mark Alban Lotz on flutes.

On a sunny afternoon in Amstel Park you are unexpectedly invited to join a guided tour through the lesser known areas of the park. You are curious, so you join the group that has gathered and follow them into the woods. After a labyrinthine route across small paths and non-paths, you finally come to an old stone-walled space that breathes of times gone by. You are asked to wait there and listen. The space seems to echo any sound that is uttered there. Clear echoing transforms into new sounds and musical structures as layers upon layers of echoes are added. A sound labyrinth is constructed as singers create a musical journey to even further-off places.

Echo:Labyrhinth is made possible in collaboration with Zone2Source and with support of the Amsterdams Fonds voor de Kunst.

Exploring Improvisation – Methods and Music

Hello, everyone! My name is Carole Ott and I am a professor of choral music at the University of North Carolina at Greensboro (UNCG). My research is focused on free improvisation in the choral setting and I am looking forward to visiting Amsterdam to participate in the workshop Rhythm and Time(ing) next weekend as well as observe rehearsals for the upcoming Echo: Labyrinth performance.

I plan to document The Genetic Choir’s unique methods through audio and video recording and would love to talk with choir members about their experiences. A new blog of my experiences and interest in improvisation can be found here: http://exploringimprovisation.blogspot.com/.

Through improvising with my choirs at UNCG, I have experienced the power of creating music from nothing (or from a collective willingness to allow the music to happen!) and I can’t wait to explore more!

Call for singers: “Resonance Lab” concerts 6 June and 10/11 October

Foto Roest loods overview locatie Resonance 6 juniThe Genetic Choir Ensemble will be involved in this Saturday’s “Resonance Lab” concert @Roest in Amsterdam, and you are invited as well – either as an active singer, or as audience in the evening (read below).

The same invitation to participate as a singer/soundmaker goes for 10 & 11 October 2015: a 24 hour vocal concert in Muziekgebouw aan het Ij…!

The “Resonance” concerts are an initiative of Merlijn Twaalfhoven to gather Dutch voice practitioners, choirs and vocal groups who are interested in new/unusual use of voice and improvisation. Both 6 June and 10/11 October are durational events where audience can move in an out at their own wish: a 4 hour concert this Saturday and a 24 hour (!) concert in October.

In a certain sense, 6 June is a try-out/experiment with (+/- 120 singers) for the 10/11 October event that will have even more singers, including Het Nederlands Kamerkoor.

It would be great to do a whole Genetic Choir section in the October event, which for the rest probably contains mainly more mainstream (pop/classical) music. :) Therefore we are calling for any singers who ever have been to a Genetic Choir workshop:

Do you want to be part of the singing event in October? Please let us know, so we can see how big a ‘Genetic Choir’ we can gather for 10/11 October. (write a comment to this post or contact us here.)

E-Flyer Resonance 6 juni in RoestThis Saturday, 6 June, performers of the Genetic Choir Ensemble will sing parts of the concert at Roest, and Thomas Johannsen will propose a polyrhythm experiment with all singers who are present.

You can come and listen (concert starts at 19:00 and entrance is free/donation based).

You can also come as individual singer and join the whole event (worskhops in the morning from 11:00, try-outs and active part in the concert later in the day):  Sign up on Merlijn Twaalfhoven’s website here.
