RökFlöte - Jethro Tull - The name of the album comes from "Rock Flute" as the original idea was to make an album of mostly instrumental flute music. But eventually Ian Anderson stated that he was drawn to the phrase Ragnarök with "rök" meaning destiny, course, or direction. Ian Anderson would then change "Flute" to "Flöte" to "keep with the spelling". Ian Anderson - flute, vocals / David Goodier - bass / John O'Hara - Piano, Keyboard, Hammond Organ / Scott Hammond - drums / Joe Parrish-James - guitar.
