If Tony Visconti’s earlier recordings had more than a whiff of 60s psychedelia hanging around them, as the 1970s wore on, the music became sleeker, stranger and, frankly, less childish. Nowhere is this more evident than in the radically different sound and aesthetic of Marc Bolan’s revamped T. Rex; but he wasn’t alone. After a brief, and seminal, flirtation with genre pastiche, David Bowie collaborated with Tony to realise his vision of what pop music might be decades into the future with the now legendary Berlin trilogy. Sparks made a mockery of prog and stadium rock with the high camp and pre-punk of Indiscreet. Even Thin Lizzy used their tough-guy, no-bullshit rock to predict what might pass for pop in the 1980s. In the Productionwise series finale, James and Graham discuss some of the best albums ever made, Top of the Pops, and fucking with the fabric of time.
