With four major music labels forcing their artists to boycott TVB due to contractual disputes, the station seems to be looking to Japan for replacements. Earlier this month it confirmed that heartthrob Hiroshi Tamaki will appear as a guest at the Jade Solid Gold Top 10 Awards show on January 16. TVB announced yesterday that popular bossa nova singer Lisa Ono (above) will be in town next Tuesday and Wednesday to tape a segment for next Friday's regular Jade Solid Gold variety programme. The occasion also allows the Brazilian-Japanese artist to promote her April concerts almost exactly a year after her sold-out debut at the Cultural Centre last year during the Hong Kong Arts Festival. Ono is set to perform on April 5 and 6. Tickets are HK$290 to HK$690 from Hong Kong Ticketing.
