The making of the album also provoked changes on a more intimate level. Clearly defined roles or tasks were firmly established by the time the band settled into Westside Studios in London (November 1985). Martin had cultivated a distinct and eclectic songwriting style and was confident enough to offer up his demos to those who were more focused in realising the musical aspects of his songs. In turn, the production relationship between Daniel Miller, Gareth Jones and Alan that had first been forged during the making of 'Construction Time Again' was firing on all cylinders. However, in spite of this, there were times when the studio atmosphere felt decidedly troubled and Daniel began to feel he had perhaps outstayed his welcome. "Dan and I had grown as friends and musical associates as well as developing a mutual understanding of the territory we felt Depeche Mode should be exploring. For example, our affiliation had been enhanced by spending long hours finishing off the previous LP, 'Some Great Reward', when everyone else had cleared off on their holidays. With 'Black Celebration', we also ran well over our deadline but it was perhaps when too many additional voices were brought into the equation that problems seemed to arise."
