R.Kelly premiered the sequel to his twisted and craftily campy "Trapped in the Closet" video serial with a red-carpet extravaganza in New York on Wednesday night.It's hard for anyone to explain Kelly's ghetto soap opera, which includes a gay pastor, cheating spouses, a convict named 'Twon and a well-endowed midget. In the new episodes — chapters 13 through 22, for those keeping count — he adds an old reverend, ex-con lesbians and a stuttering pimp, played by Kelly himself."I call it an alien," Kelly said of his tour-de-farce. The "alien" first appeared in 2005, when the singer-songwriter premiered "Trapped in the Closet," a five-part song series that kicked off with a man hiding in his paramour's closet as her husband comes in; each song ended with a cliffhanger.Soon afterward, Kelly released a DVD video of the series, adding seven more chapters — and with each chapter, the plot got weirder. But despite — or perhaps because — of its "Jerry Springer"-like appeal, it has become a cult classic.Kelly's upcoming September trial on child pornography charges hasn't dampened anticipation for the next installment of "Trapped": Parts of the new series have been premiering on Independent Film Channel's Web site since Monday; the DVD with the complete series hits stores on Tuesday. The IFC will show them in their entirety in September.
