Johanna Kurkela is the lead singer of progressive folk group, Auri. If you open heart and ear to the mesmerizing, hauntingly beautiful soundscapes of AURI, you might find a beacon of light inside a sonic realm untouched by today’s often scary, grim realities; a dreamscape that can be profoundly uplifting. On their third studio album, III - Candles & Beginnings' the stars have aligned yet again. Propelled by the unique and celestial voice of Johanna Kurkela, the magical textures of Nightwish mastermind Tuomas Holopainen and the almost unlimited musical palette of Nigtwish multi-instrumentalist Troy Donockley, Auri have presented a world to be unlocked with the senses, blending folk, progressive and symphonic elements, world music, pop and avantgarde.     Right after completing Nightwish’s 2024 monument Yesterwynde, the songwriting for the third chapter in Auri’s musical adventures started in 2023, with Troy writing in Yorkshire and Tuomas and Johanna working their creative magic in Kitee, Finland. By Autumn 2024, a 10-song demo was complete, setting the stage for what would become another breathtaking Auri journey. The band and their trusted engineer Tero "Teecee" Kinnunen took the mixing process to sunny Spain, letting the Andalucian vibes infuse the music whereas in March 2025 mastering was wrapped up by Tim Oliver at the legendary Real World Studios - a ground-breaking recording complex started by Peter Gabriel in 1989. The album is a tapestry of emotions - each song a world of its own, touching on childhood memories, vivid life experiences, and even a nod to one of the group’s most beloved places on Earth - The Lion Inn at Blakey Ridge, a historic spot nestled in the North York Moors and one of the most remote pubs you will ever find. Visually, the cover artwork by Pete Voutilainen, layout and watercolors by Mikko Pankasalo plus calligraphy by Johanna Kurkela provide wonderful illustrations perfectly capturing Auri’s unique musical visions. With guest musicians like Frank Van Essen (strings), Jonas Pap (cello), Juho Kanervo (basses), and the incredible drumming and percussion courtesy of Nightwish’s Kai Hahto, Auri III - Candles & Beginnings is as lush as it is atmospheric and provides astonishing dynamics. Having been a studio endeavour in the past, Auri is finally going on tour with their first-ever live European trek kicking off in August 2025, followed by summer festivals in 2026, allowing you to hear, see and feel songs from their previous two albums, as well as brand new pieces from III - Candles & Beginnings (such as the atmospheric new video's ‘Shieldmaiden’ and ‘Museum Of Childhood’). Its been a long time coming, but coming it is...

Simone Simons is the lead singer for symphonic metal group, Epica, that just released their 9th studio album, Aspiral. The album title is derived from the eponymous bronze sculpture made by Polish sculptor and painter Stanisław Szukalski back in 1965. It stands for renewal and inspiration – keywords that define Epica in 2025. In Szukalski’s work every detail is a piece of art on its own and there’s always more to the story than you initially think. The band saw this as the perfect analogy for the creation of this album: each song stands on its own with a distinctive vibe and meaning, while together they enforce each other into a monumental effort. At the same time this symbolizes EPICA’s group dynamic throughout this process: they have encouraged, inspired, and challenged each other repeatedly. Determined to achieve something that is greater than the sum of its parts, they left no stone unturned in their search for perfection. If it’s up to creative people to push boundaries, then this sextet sure did just that. When the band was preparing to write a new album, they kept this in mind: to create, you must destroy. As mentioned earlier, this meant destroying the individual ego and create as a unity. You’ll hear that this made the album even more personal and to the point. More alive and adventurous. But it also made EPICA destroy old underlying patterns to re-invent themselves and to create a bold new era for symphonic metal in general. The band felt the immense urge to focus on what really matters: emotions and melodies. In all capacities. As the new album is all about focus, the band asked contemporary sculptor Hedi Xandt (Rammstein, Ghost, Parkway Drive) to set all this into a stunning visual representation. It’s a bold statement and a homage all in one. If the number 9 represents divinity, perfection, and spiritual growth, then this album is the modern interpretation of just that. Musically, lyrically, and visually. Breathe in, breathe out, 2025 belongs to EPICA.
