In Flames, a pioneer in shaping the early Swedish melodic death metal scene during the 1990s, shifted towards an alternative metal sound starting from their album Reroute to Remain and continued until I, The Mask . This change was met with dissatisfaction among many long-time listeners who yearned for the days of The Jester Race and its successors.

In 2021, The Halo Effect emerged, comprised of five former In Flames members: vocalist Mikael Stanne, bassist Peter Iwers, drummer Daniel Svensson, guitarists Niclas Engelin and Jesper Strömblad. Their goal was to revive the essence of the classic “Gothenburg sound,” a mission they began with their excellent debut album, Days of the Lost.

In their sophomore release titled March of the Unheard, they continued to explore their ambition, promising a even more nostalgic and genuine musical journey. As stated by Mikael Stanne, the goal was primarily to have fun; however, with all the favorable responses it received, they felt increased pressure when composing this subsequent album. Niclas Engelin, one of the guitarists, commented that “March of the Unheard” is more progressive and showcases an abundance of guitars and riffs – essentially offering more in every aspect.

Thematically, March of the Unheard delves deeper into themes of individuality. The opener, “Conspire to Deceive,” brings to mind the original mid-90s Gothenburg scene with its melodic yet aggressive tone and moody atmosphere enhanced by atmospheric tones, interlocking guitar patterns, scratchy riffs, and driving percussion – all supporting Mikael Stanne’s intense vocals.

Throughout the album – as showcased in tracks like “Detonate” and “What We Become” – they maintain their fiery intensity while subtly increasing accessibility through epic guitar lines, catchier hooks, and calmer passages. However, the true excellence of March of the Unheard comes when the band ventures further from this central recipe. For instance, “This Curse of Silence” includes piano, and a choir. Possibly, in a bid to surprise devotees of Swedish melodeath, they include a marching band to further progress their sound in new and unexpected ways.

March of the Unheard is an impressive (and arguably superior) continuation of Days of the Lost’s faithful spirit. The Halo Effect effectively expands their new identity while revisiting classic trademarks from their former band, making it a must-listen for fans of old school In Flames and Swedish melodic death metal enthusiasts in general.
