Ashes of Billy are a young Danish rock trio formed near Roskilde in 2022, and their fast rise has been tied to a sound that updates grunge without treating the 1990s as a museum piece. Festival and venue bios place Daniel Aabenhus Hermann, Anton Stampe, and Johan Borgaa at the center of a band that mixes alternative rock, post-grunge, skater-punk momentum, and heavy metal bite. Playdate, The Right Place, and Obscene established the group's direct approach: thick but uncluttered guitar riffs, driving tempos, adolescent urgency, and choruses that carry enough melody to make the distortion feel purposeful. Their work with producer Tue Madsen on Obscene and mastering connections to Flemming Rasmussen situate them inside Denmark's heavier studio tradition, while shows connected to Copenhell, SPOT, Sweden Rock, and national touring underline how quickly the project moved beyond novelty. Ashes of Billy's music is still developing, but the appeal is clear: youthful energy, grunge-rooted hooks, and enough metal edge to make the songs feel more forceful than nostalgic on increasingly bigger stages.

London's Bush rode the grunge wave to massive commercial success in the mid-1990s, with Gavin Rossdale's brooding vocals and the band's heavy, radio-friendly alternative rock on 'Sixteen Stone' and 'Razorblade Suitcase' selling millions of copies worldwide. Though more popular in America than their native UK, Bush's string of hit singles including 'Glycerine,' 'Machinehead,' and 'Swallowed' made them one of the decade's defining rock acts.

Leeds trio Dinosaur Pile-Up have been delivering massive, fuzz-drenched alternative rock since forming in 2007, channeling the spirit of Pixies, Weezer, and Nirvana through walls of distortion. Frontman Matt Sherring's gift for melody shines through the noise on albums like 'Celebrity Mansions' and 'Growing Pains,' which pair pop hooks with grunge-weight heaviness. Their music became ubiquitous in action sports media and video games, bringing their anthemic sound to a wide audience.

Grandmas House are a Bristol punk and post-punk band whose music turns jagged guitar lines, blunt bass movement, and wiry vocal hooks into compact bursts of pressure. Formed in late 2018, the group came through Bristol's active independent scene with a live-first reputation, bringing riot grrrl spirit, grunge weight, surfy melodic shapes, and post-punk repetition into songs that feel scrappy without feeling careless. Early singles and EPs such as Grandmas House, Who Am I, and Anything For You show how the band can shift between clipped agitation, sarcastic bite, and choruses that land quickly. Their sound is lean rather than polished: the drums hit hard, the bass often carries the muscle, and the guitars leave room for vocals that sound tense, confrontational, and playful by turns. Grandmas House fit punk scope through both attitude and structure, with songs built for rooms where sweat and immediacy matter more than studio sheen. Their appeal comes from the way they make familiar influences feel communal and alive, turning queer punk energy, Bristol grit, and a sharp sense of humor into music with real forward motion.

Hathors are a Swiss noise-rock trio from Winterthur who deliver a raw, visceral blend of grunge, punk, and hardcore that feels like it was recorded in a collapsing building. The band's stripped-down approach channels the confrontational energy of Melvins and early Mudhoney through a distinctly European sensibility. Their albums showcase a relentless commitment to volume and distortion as artistic statements rather than mere sonic choices.

HotWax are a Hastings-born alternative rock band whose music revives the physical rush of grunge, post-punk, and noisy guitar pop without sounding like a museum exercise. Built around Tallulah Sim-Savage, Lola Sam, and drummer Alfie Sayers, the group developed from teenage beginnings into a touring act known for direct, high-energy performances. Their songs use fuzzed riffs, quick melodic turns, and restless rhythms, often balancing a loose, almost garage-like force with hooks that are easy to remember. HotWax fit rock and punk-adjacent scope through the way they draw on heavy 1990s alternative music, post-punk invention, and grunge dynamics. Tracks from EPs and the album Hot Shock show a band interested in impact: bass lines are thick, guitar tones are abrasive, and the vocals cut through with a mix of cool restraint and sudden heat. There is youthful urgency in the music, but also discipline in how the parts are arranged. HotWax's strongest moments feel like a room getting louder in real time, with the band using familiar distortion and swing to create songs that are bold, kinetic, and built for close-range stages.

Leicester trio Mouth Culture bring an authentic, scrappy energy to UK alternative rock, blending pop-punk hooks, grunge grit, and indie sensibility into a sound that has earned comparisons to early You Me At Six. Vocalist Jack Voss, bassist Todd Groome, and guitarist Mason Clifford all live together, channeling their shared life into the relatable, high-energy songwriting heard on their EP 'Whatever The Weather.' Their fast rise through the UK alternative scene includes opening for You Me At Six on their European farewell dates.

Bergen, Norway's Slomosa channel their icy Nordic surroundings into what they call 'tundra rock,' a distinctive hybrid of stoner rock riffage, grungy hooks, and concentrated punk energy inspired by Kyuss, Elder, and Black Sabbath. Their 2024 sophomore album 'Tundra Rock' won Best Rock Album at Norway's Spellemannprisen awards, validating the band's vision of transplanting the sun-baked desert rock sound to Scandinavian terrain. Benjamin Berdous and Marie Moe's shared vocal duties add a melodic versatility that complements the band's thunderous, groove-laden guitar work.

Fronted by Gene Gallagher, son of Oasis legend Liam Gallagher, Villanelle channel late Nirvana grunge through a lens of lo-fi grit and arena-sized swagger. The UK trio sold out a headline tour before even releasing a single, building a fervent following purely on the strength of their incendiary live shows.
