Pain started out as a hobby project for front man Peter Tägtgren, whose idea was to fuse metal with 1980's-inspired electro-industrial and techno influences.

During the Dark Passion Play World Tour with Nightwish, singer Peter Tägtgren, drummer David Wallin and bassist Johan Husgafvel were assaulted by a gang in Leipzig. Peter received 10 stitches in his face, David suffered a concussion and Johan had his nose broken.

During the recording of the album "Dancing with the Dead", Peter Tägtgren's heart stopped beating for several seconds. This event inspired him to write the song "Dancing with the Dead."
