Dahlqvist's next project was Strängen, the Swedish translation of his nickname "Strings" from his time with the Hellacopters. He released the single "Rocken är inte död!" ("Rock Isn't Dead!") under this name, and announced a new album which would be his first full-length work in five years. According to his manager, the album was nearly finished at the time of Dahlqvist's death in February 2017, with some of the final sessions having taken place a few days earlier. Dahlqvist died on 1 February 2017 at age 40. Sound Pollution, distributor for the Hellacopters, stated that Dahlqvist died accidentally at home, having drowned in a bathtub following an epileptic seizure. At the time of his death, he had several concerts and appearances scheduled for the coming weeks. Dahlqvist favoured vintage guitars, effects and amplifiers.
