Trettioåriga Kriget(Thirty Years War) was formed in 1970 in Saltsjöbaden, a seaside resort southeast of Stockholm. They were at the time all around seventeen and still in high school. The schools main hall was in the beginning used as the rehearsal room. This first lineup of the band was a six piece with two drummers! It included Stefan Fredin- bass guitar, vocals, Pocke Öhrström- guitar, vocals, Dag Lundquist- drums, Olle Thörnvall- harmonica, guitar, Dag Kronlund- piano and Johan Gullberg- drums. In 1971 Pocke, Johan and Dag K. left and Robert joined on vocals and guitar. In 1972 Olle quit playing harmonica to concentrate on the lyrics, leaving the band to consist only of Stefan, Dag and Robert. They decided they needed a good guitar player and started to audition some guitarists. Through these auditions they found Christer who joined the band in summer 1972. The band rehearsed intensively for a year and a half and developed a style of their own quite unlike the main trend in Swedish rock during the Seventies. ..

Early 1974 they got a record deal. Also at that time they got a new rehearsal room in Saltsjöbaden. An old underground disco which they called “Grunden”. There they would remain for a long time….An album was recorded that summer and released in august 1974. The album was named only “TRETTIOÅRIGA KRIGET”. The musical talent and originality of the group was duly recognized in the reviews. The album was an instant classic and is often considered as the first Swedsih heavy rock album. They also now started to tour extensively in Sweden and also did several live performances on national Swedish radio. ..

The second album “KRIGSSÅNG” was recorded in the summer of 1975 though it was not released until early 1976 . It is commonly regarded as Trettioåriga Krigets “masterpiece”. The second side is totally devoted to the long suite “Krigssång 2″. These first 2 albums have had a tremendous influence on later Swedish progressive and metal bands i.e. Anekdoten, Opeth, Änglagård etc. The band continued touring and gigging in -75 and -76 . In October -76 they left for an extensive English tour from Croydon in London to Cardiff in Wales to Sunderland near the Scottish border. They went down very well and the English music magazine “Melody Maker” chose them as one of the most promising bands for -77, speaking enthusiastically of their “intense gripping songs” and saying that “the power of the music is tremendous”!!! Back home again however they got the boot from their Swedish label, who apparently hadn..t heard any news from abroad. .. Trettioåriga Kriget then chose to sign for a small Swedish independet label called Mistlur.

The first album on this new label was called “HEJ PÅ ER”.It was recorded in the summer of 1978 in “Grunden”, the rehearsal room, with mobile recording facilities. By this time Mats had joined on keyboards too. The album was very well received and was to that date their best selling album. The album was seeing the band moving to a more simple song format and is seen as the last album in a trilogy starting with the first album. The band continued to tour extensively during this time around Scandinavia. ..

In the summer of 1979 the band recorded “MOT ALLA ODDS” also at “Grunden”. It is largely regarded the bands least successful album though it has its moments, i.e. the title song. This was the last album with Robert who left in autumn 1979 leaving the vocals to Stefan. .

.In 1980 the band played the Roskilde festival in Denmark and continued the extensive touring. And they also recorded their fifth album called only “KRIGET” which was released in spring 1981. It got some some very good reviews and was played a lot on Swedish radio. Even so the band felt that
energy was running out after 7 years of touring plus 5 albums and decided to split.

The story then jumps to 1992 when Stefan, Robert and Dag played an acoustic set at a releaseparty for the CD-release of “Krigssång”. And then in 1996 to coincide with the release of their mostly live album “WAR MEMORIES”, the band decided to do two reunion concerts in Stockholm… ..

In 2002 Stefan, Dag, Chris and Olle decided to start rehearsing to try out new material. These rehearsals were such a success that the band decided to enter the studio once more and record a new album. In the studio, Robert and Mats also joined. The album was named “ELDEN AV ÅR” (Fire of Years) and was released January 2004. It got such very good reception and reviews. Many describing the album as the bands best and even one of the best reunion albums ever released. Live shows also followed in 2004 with the classic lineup of Stefan Fredin, Dag Lundquist, Christer Åkerberg, Robert Zima and Mats Lindberg. In September 2004 the band even made their US debut playing the Progday Festival in North Carolina and also for the first time in over 30 years did a show in their home village of Saltsjöbaden. .. Later that autumn their first two albums, “Trettioåriga Kriget” and “Krigssång” were re-released with bonus tracks. In March 2005 the bands third album, “Hej på er” (Hallo everybody) was also re-released with bonus tracks. .. In June 2005 they played Swedens biggest rockfestival, Sweden Rock, and in March 2006 they played the Baja Prog Festival in Mexico. ..

In 2004 TK also released “GLORIOUS WAR” an album recorded in 1971 by the founding lineup of the band but put in the archives and not released until 2004.

In August 2007 their 8th studioalbum, “I BÖRJAN OCH SLUTET”(In the beginning and the end), was released to overwhelming reviews. The band saw it like a natural follow up to “Elden av år”, with a more coherent atmosphere, and unlike “Elden” this album was written and recorded in a shorter space of time. Autumn 2007 also saw the band play in both France and Brazil for the first time as well as some Swedish shows to promote the album .. Spring 2008 saw the band play in Spain for the first time as well as shows in Norway, Sweden and France. .. In the autumn of 2008 the band did release their first live album called “WAR YEARS”. A double album covering their whole career from their 2nd show ever in their home village of Saltsjöbaden up their show at the Progday Festival in North Carolina, US in 2004. They also made their first tour of Japan and to coincide with the tour released their first 3 and 2 latest albums there in a boxset called just “TRETTIOÅRIGA KRIGET”. .. In June 2009 TK played the prestigious Nearfest Festival in the US…

In April 2011 TK released the last album in the trilogy starting with “Elden av år” and “I början och slutet” called “EFTER EFTER” (After efter). In the autumn of 2011 the band is did their first shows in Chile and Peru plus in Stockholm for the first time ever performed their debut album from 1974 in its entirety.

Autumn 2012 saw TK doing their first ever show in Italy plus a handful of shows in their home country Sweden. Including a headlining appearance at the “Sweden Prog Fest” festival where they for the first time ever played their masterpiece album “Krigssang” in its entirety.
2013 started with a show in Tokyo, Japan in January. It will be followed by an appearance at the Melloboat cruise Stockholm-Riga together with among others Opeth, Änglagård, Devin Townsend. This will be the last TK show for some time because work will start
on a new album. Plans are also underway for finally re-releasing the 4th and 5th TK albums (“Mot alla odds” and “Kriget”) digitally and on CD.

In March 2016 TKs first English language album,”SEASIDE AIR”, was released to overwhelming reviews. The album has more emphasis on vocals than the other TK albums using all three TK singers, Robert, Stefan and Dag, a lot.
Spring 2017 will see TK doing their first shows for almost a year in Oslo, Warzaw and Stockholm.
