The promise of three strong days with distinct musical highlights for next summer’s festival in Plovdiv is becoming increasingly clear.
ELECTRIC CALLBOY join HILLS OF ROCK 2026 after hundreds of fan requests and with the reputation of being one of the most striking phenomena in Europe’s modern metal scene.

ELECTRIC CALLBOY sell out global tours, host their own festival, grow rapidly across social media, and are known for their distinctive hairstyles and recognizable fashion style, making them a true pop-cultural force. Expect energy, irony, and carefree rage on stage – Plovdiv, you’re not ready for them!

LAMB OF GOD stand as one of the most important bands in modern metal. Emerging in the early 2000s, they tore down the boundaries between mainstream and underground with a merciless sound that combined crushing groove metal and venomous thrash, offering the perfect alternative to post-grunge and nu metal — all powered by Randy Blythe’s infernal roar.
With albums like Ashes of the Wake and Sacrament, Lamb of God became a driving force of an entire era — the New Wave of American Heavy Metal (NWOAHM) — proving that even the most extreme forms of metal can dominate global charts. Their long-awaited Bulgarian debut will deliver both classic hits and new experiments that continue to shape not only their sound but the genre as a whole.

For the next band, everything begins and ends with the riff. BLACK LABEL SOCIETY join HILLS OF ROCK 2026 carrying the full weight, tradition, and power of American hard rock. Led by Zakk Wylde – a legendary guitarist known for his signature tone and commanding stage presence — the band is built around one simple but fundamental rule: the guitar is god.
From studio to stage, BLACK LABEL SOCIETY are a mix of raw blues, relentless groove, and unfiltered rock’n’roll, a living machine that feels part onslaught, part wandering carnival, fueled by noise, fire, and emotion
