Sofia Live Festival opens the door to its sixth edition with a powerful lineup, taking place on 27 and 28 June 2026 at Vidas Art Arena in Borisova Gradina, Sofia. The festival continues its mission to bring together some of the most exciting names from the international rock, alternative and electronic scenes alongside standout regional artists.

The first festival day, 27 June, will feature British post-punk phenomenon IDLES, performing in Bulgaria for the very first time. Known for their explosive live shows and uncompromising sound, the band move confidently across the territories of punk and its subgenres, from post-punk to art-punk, delivering sharp guitar riffs, raw energy and lyrics addressing themes such as unity, identity and social tension.

Joining them the same evening are multi-platinum rock band Three Days Grace, who return to Bulgaria with their original vocalist Adam Gontier, reunited with the band for a new chapter in their career. With billions of streams, millions of albums sold and 19 No.1 rock singles, the Canadian band remain one of the most successful rock acts of the past two decades, known for powerful anthems like “I Hate Everything About You” and “Never Too Late”.

The lineup for 27 June also includes Serbian indie-rock band KOIKOI, one of the most exciting emerging acts from the region. Blending indie rock, electronica and post-punk, the Belgrade-based group have performed across Europe and appeared at major festivals such as Reeperbahn Festival, Fusion Festival and Eurosonic, steadily building an international following. Bulgarian band Strugare will also join the opening day of the festival.

On 28 June, the festival welcomes legendary electronic pioneers Underworld as headliners. The duo Rick Smith and Karl Hyde have shaped the global electronic music landscape for over three decades, from their groundbreaking album dubnobasswithmyheadman to the generation-defining anthem “Born Slippy (Nuxx)”.

In recent years Underworld have experienced a new creative renaissance, with sold-out tours, headline festival appearances and collaborations with artists such as Brutalismus 3000, KETTAMA and KI/KI. Known for their immersive and euphoric live performances, they remain one of the most influential and enduring acts in electronic music.

With its carefully curated program and international lineup, Sofia Live Festival continues to establish itself as one of the most distinctive boutique festivals in the region.
