Warner Music International CEO Patrick Vien will deliver a keynote interview at this year's London Calling trade fair, to be held June 28-29 at the Earls Court venue.

Vien will use the platform of the annual conference to discuss how the music giant is adapting and positioning itself in the new media age.

Other participants at the conference include David Bowie producer Tony Visconti, IFPI chairman John Kennedy and AIM CEO/WIN president Alison Wenham.

Meanwhile, artists Chris Difford and Glenn Tilbrook, the songwriting duo of '80s British hitmakers Squeeze, will take part in a "How Did They Do That" forum, which will be hosted by the BPI.

The London Calling program will also feature live music, showcases, gigs, parties and networking events.
