AS IF we weren't already over-dosing on gigging treats ranging from Gerry and the Pacemakers to INXS, Bob Dylan and Michael Bolton, a couple of new big name acts have entered the frame. There is talk of Hong Kong shows by Duran Duran on April 2 and UB40 on May 2. That talk is coming from Frontier, an Australian promoter which is hoping to pull a deal here. Frontier's arrival on the scene is indicative of the changing nature of local rock promotion. Marathon-running Canto-pop concerts are now a thing of the past and that leaves previously booked-up venues free for overseas performers. Glance through a venue's bookings today and you will see a host of new promoters' names. One of the more established impresarios, Anders Nelsson, the man responsible for bringing INXS, Bob Dylan and Michael Bolton to Hong Kong, doesn't mind. He foresees aday when Hong Kong people will pick up a Time Out to decide on which show to see that night. However, he is not too optimistic about the soon-to-be-opened Hong Kong Stadium, saying: 'It's bad enough matching the artist's and the venue's availability, not to mention the risk of a change of weather.' For now, Nelsson is returning to bread-and-butter work, with the opening of a new studio in North Point. Gerry and the Pacemakers will be guest performers at Tuesday launch bash at the Ritz-Carlton hotel. Meanwhile, speculation has been rife over the direction rock band Beyond will take now that its contract with Warner Music has expired. The band, who lost lead singer Wong Kar-kui in a stage accident in Tokyo last year, are said by reliable sources to favour Rock Records. The ambitious Taiwan-based company will handle the distribution of Beyond's records in both Mandarin and Cantonese for Southeast Asia.
