Trettioåriga Kriget — Swedish for ‘the Thirty Years’ War’ — are one of the most respected and influential progressive rock bands ever to come out of Sweden. Dark, heavy and steeped in the spirit of King Crimson, they built a dramatic, mellotron-drenched sound all their own, sung entirely in Swedish, and became godfathers to a whole later generation of Scandinavian prog.

The short version

Trettioåriga Kriget are a Swedish progressive rock band, formed near Stockholm in 1970. Their music is dark, dynamic and heavy — King Crimson’s influence run through with hard rock, mellotron and jazzy, psychedelic detail, and sung in their native Swedish. The three albums here span their classic era, from the landmark 1974 debut and its acclaimed follow-up “Krigssång” (1975) to the poppier “Mot alla odds” (1979).

A history lesson and a name

The band came together in 1970 in the seaside town of Saltsjöbaden, formed by high-school friends Stefan Fredin and Olle Thörnvall — who, the story goes, settled on the name after a history class on the Thirty Years’ War, because it sounded ‘powerful and Swedish.’ They started as a six-piece with two drummers. After some early changes, the classic line-up fell into place: singer Robert Zima joined in 1971, guitarist Christer Åkerberg in 1972, and Olle Thörnvall put down his harmonica to become the band’s dedicated lyricist.

Dark, heavy and unmistakably Swedish

Signed to CBS, Trettioåriga Kriget made their name with a sound quite unlike anything else in early-1970s Sweden. Where much of the local scene leaned folk and psychedelic, they went dark and heavy — the fiery attack of King Crimson crossed with the muscle of Deep Purple and Uriah Heep, washed in mellotron and shot through with jazzy, unexpected turns. Fredin’s bass often leads like a second guitar, Zima’s vocals are urgent and dramatic, and, boldly, everything is sung in Swedish — giving the music a character entirely its own.

From the classics to the split

The self-titled debut (1974) and “Krigssång” (1975) are the band’s enduring classics, the latter often hailed as their masterpiece. After being dropped by CBS, they moved to the independent Mistlur label and gradually streamlined their sound — adding keyboardist Mats Lindberg — on “Hej på er” (1978) and the poppier “Mot alla odds” (1979), after which Robert Zima left. The band carried on briefly before splitting in 1981, but their story was far from over.

The players

The classic Trettioåriga Kriget centred on singer Robert Zima, guitarist Christer Åkerberg, bassist Stefan Fredin and drummer Dag Lundquist, with founder Olle Thörnvall as the band’s lyricist and keyboardist Mats Lindberg joining in the late 1970s. Remarkably, that core has held together for decades: the band reunited permanently in 2003 and has kept recording ever since, releasing new albums right up to the 2020s and passing its fiftieth anniversary with the classic line-up still largely intact.

Where to start

Start with “Krigssång” (1975) — for many the band’s masterpiece, home to its epic, side-long title suite — or the raw, aggressive self-titled debut (1974), which captures their dark, Crimson-inspired power at its most thrilling. “Mot alla odds” (1979) is a lighter, poppier and more divisive record, best saved for later. The first two albums are the essential Trettioåriga Kriget.

Why they still matter

Trettioåriga Kriget matter as pioneers — among the very first true progressive rock bands in Sweden, and among the finest. Their dark, heavy, Crimson-influenced sound, sung defiantly in Swedish, proved deeply influential, echoing through later Swedish greats like Änglagård and Anekdoten. Few bands of their era have aged so well or endured so long. For anyone drawn to King Crimson, to Scandinavian prog, or simply to music of real power and atmosphere, Trettioåriga Kriget are essential.
