Over 450 record labels will be present at the networking event, as well as some of the world's most important music and DJ equipment companies, such as Juno, Myspace, EMI, Ministry of Sound, Pioneer, Ableton, Computer DJ, Positiva, Ninja Tunes, and DJmag, of course.
London Calling launched last year, and although there were some teething problems with clashing sound levels in the venue, this year's event looks likely to be a major occasion.
Some big name DJs will also be showcasing and demonstrating their skills at London Calling, including James Zabiela, Krafty Kuts, Rennie Pilgrim, Omid 16b, and Demi.
