A soon-to-be-released documentary could shed light on what was the beginning of the end of a hip hop dynasty. Filmmaker Choke No Choke tells Hip Hop Weekly that his movie about the rise and fall of Roc-A-Fella records, co-founded by Jay-Z and Damon Dash, will raise eyebrows: “Both Jay and Dame was involved with a certain R&B singer, who I’m not gonna say her name out of respect ’cause she ain’t around to defend herself, but I believe that was a part of the initial friction. I was seeing Jay with her back around 2000, then Dame was with her after. All you have to do is look at the movie they did, Death of a Dynasty. In the movie they were fighting over a model. In real life, she was a model, but singing is what she was known for first.” Photos have surfaced on the Web, showing the late singer Aaliyah in poses with both Jay and Dame. The singer’s body language suggests that she’s comfortable with a shirtless Dash, but Jigga is shown with an arm wrapped rather intimately around her waist in a pre-Beyonce’ pose or two. Aaliyah died in a 2001 plane crash.

Americans, Jamaican compete in British Grand Prix.

Tyson Gay has won the 200-meter dash in 20.26 seconds, while Asafa Powell grabbed a 9.87 victory in the 100 at the British Grand Prix. The sprinters, who both missed individual golds at the recent Beijing Olympics, shined during Sunday’s competition in London . Powell had anchored Jamaica ’s world-record-breaking, gold relay team in China , but was disappointed with his fifth-place finish in the 100. American Lauryn Williams, who was involved in the baton-dropping fiasco of the women’s 4×100 relay at Beijing , beat Olympics champ Shelly-Ann Fraser in the Grand Prix’s 100, a race that featured five Beijing finalists.

Damon Dash dropped from deal.

More bad news for the Roc-a-Fella Records co-founder who recently had news of his pending home foreclosure hit headlines: Damon Dash recently lost his licensing agreement with Pro-Keds. Dash had actually given the impression that he bought the old-school sneaker company. He spoke of plans to make the lesser-name brand hip for a new generation. But now the brand has terminated Dash’s deal. The entrepreneur has yet to strike gold as he did when he helped found the record label that helped make his ex-partner, Jay-Z, a superstar.
