 From January to March 1974, Focus recorded "Hamburger Concerto" at Olympic Studios with Vernon.Recording was met with growing tension, with van Leer, Ruiter and Allen working together during the day and Akkerman recording his parts in the evening.The album presents further classical music influences, opening with "Delitæ Musicæ", a lute piece Akkerman adapted from "Delitæ Musicæ Cantiones" by Dutch composer Joachim van den Hove.
