Conrad will perform at the Swedish Pop In The Park Festival in Stockholm on June, 9th at C@fé Opera! As far as I understand the swedish info site, the event is for free, the event is hosted through donations. Below some infos that the site tell:
“Australian singer Conrad Sewell got international fame with “Start Again”. He´s also the voice of Kygo´s “Firestone”. Now he comes to Stockholm to play live at Pop In The Park”. The event has a capacity for approximately 10.000 guests.
