Aggregation: The Architects of Modern Progressive Metal

Aggregation is a progressive metal band from Oslo, Norway, known for their complex compositions and technical precision. Their 2018 album, The Sum of All Parts, debuted at number 12 on the Norwegian album chart and solidified their reputation as a leading force in the genre.

Early career

Formed in 2008 by guitarist Lars Vik and drummer Henrik Solberg, Aggregation began as a project to fuse melodic death metal with intricate, jazz-influenced rhythms. The band self-released their debut EP, First Principles, in 2010, which caught the attention of the independent label Indie Recordings.

Signing with Indie Recordings in 2011, they spent the next two years meticulously crafting their first full-length album. This period of intense writing and rehearsal defined their signature sound: a dense aggregation of shifting time signatures and harmonically rich guitar work.

Breakthrough

The band's breakthrough arrived in 2015 with their sophomore album, Emergent Properties. Released again via Indie Recordings, the album received critical acclaim within the European metal press for its ambitious scope.

While not a mainstream chart smash, Emergent Properties achieved gold certification in Norway for streaming equivalents, a notable feat for a progressive metal act. This success provided the momentum for their subsequent charting album and wider international touring.
