In 2005, Burning Heart Records reported that The Lost Patrol has grown from Lyxzén's solo project into a full-fledged band. This is reflected in the title of the 2005 album "The Lost Patrol Band". The album also represents a further change in style, this time encompassing the upbeat sounds of 1970s/'80s punk and power pop. In 2013 the group signed to Razor & Tie and changed their name to INVSN. In 2010 Invasionen released their debut album Hela Världen Brinner on Sony Music in Sweden. A vinyl version of the record was released on Dennis' own label Ny Våg Records. Shortly after the record was released Robert Pettersson left the band to focus on his band Masshysteri. Richard Österman replaced him on bass. Since the album was only released in Sweden and the lyrics were in Swedish they mainly just touring Sweden but also did some shows in Spain. The first album "Hela Världen Brinner" could be described as a tribute to early Swedish punkrock. In the fall of 2011 the sophomore album "Saker Som jag Sagt Till Natten" was released once again on Sony Music. The album got good reviews in Sweden and when they started playing shows Sara Almgren from Masshysteri had joined the band on bas and Richard had moved to guitar due to Anders touring duties with Lykke Li. The album had a darker and more serious tone then the previous album. In the fall of 2011 they also did a tour of China before touring Scandinavia. In 2012 the band was largely on a break due to Dennis Lyxzén's commitment to the Refused reunion. They still managed to play over 20 shows and write the material that would end up on their next record. In 2013 the group recorded their third album and signed to Razor & Tie and changed their name to INVSN (Pronounced "Invasion"). The record was recorded in both English for an international Release and Swedish for a domestic release in Sweden. The english version of the album was released on 24 September and the band set out on a tour in North America supporting Minus The Bear. Before the tour Richard Österman stepped down from touring duties and Christina Karlsson and Kajsa Bergsten joined. During 2013-2014 the band did over 110 shows all over the world. 2 Tours of North America, a trip to Cuba and a couple of European tours, one with Against Me!. The Album got great reviews in Europe but not much happened in America due to a lack of interest on the labels part.
