How can I participate in Sónar Calling GJ273b?

Do you have a message for extra-terrestrials?

Be part of this groundbreaking experience. Send us your musical piece and participate in our second transmission! Three selected pieces created by the audience will be joining the 33 artist’s tracks at the end of April 2018 to be sent beyond the solar system. The authors of the selected pieces will be also invited to join us to celebrate the 25th years of Sónar with three more guests.

Conditions of participation

Only original musical pieces composed exclusively for the Sónar Calling transmissions to Luyten's Star b will be accepted. You can upload your 10 seconds long .wav file using the form on our webpage. We recommend that you take into consideration the imposed digital format limitations being used in the transmissions. The very low quality will mean that the high frequencies (above 4kHz) will be lost, as well as faint sounds and stereo effects.

The deadline is March 1, 2018. The three pieces selected will be announced by April 23, 2018 at the latest. Each of the three participants selected will receive 2 VIP Passes to attend the 25th Sónar Festival in Barcelona 14.15.16 June 2018. Consult the terms & conditions.
