The winners of the WWF and radio Tangra Mega Rock contest were absolutely delighted with their performance on Saturday.

Thousands of people showed up in front of the 'Ivan Vazov' National Theatre in Sofia - Bulgaria. ProceedingsВ kicked off exactly one hour before the big electricity blackout - at 7:30 p.m. local time.

"The live show was absolutely fantastic" said CUTT in an open letter to the Bulgarian media.

"Thanks to everyone who supported us. Thanks to the fans who sang along. We are hugely impressed by this event. It was great and very inspiring for us".
