In 2013 Kavarna Rock Festival became for the second time the home for some of the biggest names in rock and heavy metal. 1-2 August 2013 fans got together under the skies of Kavarna and became part of one of the most significant events of the summer. Deep Purple who had not released an album since 2005 chose to present their new album "Now What?!" for the first time in Europe before their Bulgarian fans.

The festival hosted a multitude of bands, both International and Bulgarian. On the first day, the fans met the famous Bulgarian band Cherno Feredje followed by Thunder and Aria. Having recorded nine albums, two of which has reached the top of the UK album charts, Thunder had a special place on this year's stage in Kavarna. The stage also welcomed Russian rock legends Aria. The frenzy in the pit intensified when the band, known as "Iron Maiden of the East" hit the stage. Headliners for the first festival evening were the German metal machines Accept.

Bulgarian heavy metal band Analgin and the emblematic voice of singer Zvezdi Keremidchiev kicked-off the second day of the festival. Followed by Doro Pesch - the German heavy metal queen, that has proven over the years that women stand equal to men when heavy music is concerned. Doro performed some of her biggest hits like "Raise Your Fist in the Air", "All We Are" and "Für Immer".

Along with their classics, Russian band Alisa performed songs from their 2012 album "Sabotage", which is considered the best album in their thirty-year long career. The headliners - the rock giants Deep Purple were the culmination of the second day of the festival.
