The Wall Street Journal has brought back its Tech Cafe for another run in London on 25 and 26 September. It will host a series of free-to-attend events and panel discussions featuring technology entrepreneurs, developers and venture capitalists who will be talking about the hottest topics in the technology industry.

Among those will be Pink Floyd's drummer Nick Mason, who will discussing digital music copyright and the unlocking of the band's entire back catalogue on Spotify. Other guest panellists to appear over the two days include Mark Forster, UK managing director of Deezer.

The event takes place in the Rotary Bar & Diner in London's Shoreditch. You can find out more information, an agenda and registration details on the official website.

"The Wall Street Journal has a strong global reputation for breaking technology news and inspiring compelling industry discussion," said WSJ technology editor Ben Rooney.

"In London we have one of the world's most innovative and promising clusters of tech companies on our doorstep and the Tech Cafe brings these exciting, astute minds together for engaging conversation, insight and advice.  We saw last year the appetite for learning among the creative minds in Tech City and look forward to setting up again."
