LOS ANGELES (Reuters) - R&B singer Chris Brown announced a month long fan appreciation tour on Tuesday the same day that ex-girlfriend Rihanna released a new single seen by some as evoking their stormy relationship. Both Rihannas single Russian Roulette and Browns tour announcement were firsts since their relationship came to a violent end in February. Brown, 20, was sentenced to five years probation and community service in August for a bloody attack on Rihanna, 21, on the eve of the Grammy Awards in February. He has since publicly apologized for the assault, but has remained largely out of the media spotlight. Browns record company Jive said the Kiss Kiss singer would play small venues in 19 U.S. cities starting in Houston, Texas on November 14. Billed a fan appreciation tour it is intended to thank his followers for their support, Jive said. A portion of the proceeds will be donated to a Los Angeles domestic violence intervention charity called the Jenesse Centre, and an organisation providing friendships and jobs for people with developmental disabilities called Best Buddies International. Browns new single I Can Transform Ya was released in late September. Rihannas first single from her upcoming album Rated R, with rival label Def Jam Records, tells the story of a woman faced with a game of Russian roulette. You can see it through my chest/That Im terrified/But Im not leaving/I know that I must pass this test/So just pull the trigger, part of the lyrics read. Rolling Stone.com described it as a dark ballad that ends with an ominous gunshot and seems to find Rihanna singing about enduring a tumultuous relationship. Both Brown and Rihanna were among the fastest rising R&B artists in the United States before the assault, which led to Brown losing several commercial sponsorships and triggered a national debate about violent relationships.
