If two men of passion and talent

– One from Caracas, Venezuela

– One from Córdoba, Argentina

Learn about each other's existence

On the world stage called Madrid

What could happen?

No rivalries or dramas,

But the human miracle of music:

Omar Acosta said flute,

Classical guitar, responded Sergio Menem.

They started playing their memories of Latin America

Twisting in jazz with hindu ornaments,

Embroidering flamenco stitches

Onto the fine fabric of an album they baptised

Entretiempo y Tiempo – Meanwhile and While

It opens with Pastora

Omar’s specific, vivid painting of Venezuelan planes

With a figure of a shepherdess – is it his grandmother who did not let him play with other kids unless he had studied music? – on the horizon

To which Sergio responds with Chorinho pra Jaques

His musical love letter to his teacher Jaques Morelenbaum

A legendary composer and arranger of the most iconic Brazilian albums we all know without knowing.

Conversing through music on every imaginable topic

From mysticism in Ave Maria to exchanging imaginary dance steps in Sevillanas Criollas

Omar and Sergio are what official press releases call an acoustic duo, and what we in Invisible City call the two friends we have always wanted to have!

Who is organising this concert?

Invisible City, a non-profit on a mission to enable emerging artists to perform more and get paid fairly.

How do I see the concert?

Once you have made your donation, we’ll send you an online ticket with a secret code to our invisible private room in Zoom, for which we have a professional account for maximum quality. We do NOT RECORD the concerts and keep our virtual room intimate and cosy, limiting the participation to 35 people.

Will I have a good sound?

We make sure that the artists have the fastest internet connection possible and are properly geared. We run numerous soundchecks prior to the concert to make sure everything is tuned on the artist side! You can do your part: make sure your setup is as perfect as possible with our self-soundcheck guide.

How much should I donate?

We encourage you to make a donation on behalf of every person who participates in this online concert together with you.

We believe that 4 euros per person is fair, yet most guests usually contribute around 9 euros, so if you have the means and wish to support the artists and Invisible City further, we’d be grateful if your donation corresponds to what feels fairest to you.

You can also make a donation directly to the Invisible City account (for example, from your Revolut app or similar):

Account name: Invisible City MTÜ

IBAN: EE88 7700 7710 0336 8942


(Depending on your bank, the transfer may take some time to arrive, this is why please send us an email at letting us know you made a transfer so that we send you your ticket right away!)

How much does the artist actually get?

Even before the gig starts, Invisible City guarantees a minimum of 100 euros to the artist no matter what. This is our investment into the performance which provides a safety net for the artist. We make sure it is never a lottery! These funds come from reinvesting the donations from the previous performances as well as from our private sponsors who support Invisible City directly (here is how you can become one).

What the campaign receives above the 100 euro mark, we share with the artist in equal parts. In this way, we provide a guaranteed income to the artist while staying sustainable and helping more artists run more wonderful gigs.

How do I pay in my currency?

If your bank does not allow foreign payments, just write to us at and we find a way, promise!

Do you have Apple/Google Pay?

Yes. When you click on 'donate' the Apple/Google Pay option will appear automatically.

I need further help with donating!
