As heavy metal continues to diversify and fragment into numerous sub-genres, it’s heartening that there are bands like Aeonblack playing the traditional variant. With roots stretching back to the late 1980’s, things really started moving for this Lörrach (Baden-Württemberg, Germany) crew when they settled on their current moniker in 2003. Throughout the years they’ve kept the faith and have released two albums full of bombastic metal, and their third long player, Treason, continues a similar trajectory. However, their loyalty to the genre doesn’t mean they are stuck in the past, far from it, by taking the best from metal’s history and playing with an intensity that places them right in the present, Treason signposts a bright future.

If there were any doubts about Aeonblack’s verve and vitality then they are succinctly blown away by opening (and title) track ‘Treason’. There’s no time to waste on fancy introductions or preambles, Aeonblack appear like a bullet from a gun and it is all the more powerful for its sudden arrival. With soaring vocals and screaming guitars, alongside a rumbustious rhythm section, ‘Treason’ (and, indeed, the whole album) encapsulates all that’s great about heavy metal. Think of every great album from 1982 (Metal On Metal, Blackout, One Vice At A Time), roll them into one and you have something approaching the sound of Treason. It’s turbo charged and captures that moment in time when metal was morphing into thrash. Yet, there’s a contemporary edge to ensure that Aeonblack are no retro act. It’s a unique sound the band have formulated that incorporates elements of power and symphonic metal and ensures that Treason is at once fresh and familiar.

With only one of the album’s nine tracks clocking in at under four minutes (the interlude ‘I Am Become Death’) and most over five, Aeonblack build soundscapes that are vivid and vibrant. Songs such as ‘Death By AI’ and ‘As The Sun’ are mini novellas set to music that create a sense of place and time, placing the listener in the heart of the action. While much of Treason is a foot-on-the-monitor, horns-held-high, neck-snapping celebration of heavy metal, Aeonblack have a lot of kit in their toolbox, mixing up tempos and rhythms to great effect to ensure the album never stagnates. It gives the band a lot of musical freedom and they put it to good use, inserting moody and atmospheric tracks such as ‘All Has Read’ to ensure the album ebbs and flows perfectly. Lyrically, too, Aeonblack avoid the usual “sword and sorcery” themes, instead grappling with conspiracy theories (‘What Dwells’) and technofear (the aforementioned ‘Death By AI’). However, as with the music, the band’s lyricism is a nice mix of the traditional and the modern, the former being represented by the H.P. Lovecraft inspired ‘All Has Read’.

This album is dedicated to the band’s bassist Roland Zehrer and is to be released on the first anniversary of his death. Treason not only makes a fitting tribute, but renders Aeonblack a contemporary force.
