Still fine-tuning its identity before taking over as the new Twins broadcaster, Pohlad-owned radio station K-TWIN (96.3 FM) has lifted some well-known personalities from Cities 97 and KARE-11.

Former Cities FM morning show host Brian "B.T." Turner will become the noontime jockey on K-TWIN starting Jan. 2, which is also the date Rena Sarigianopoulos begins her new duties as co-host of K-TWIN's morning show alongside her longtime KARE-11 TV cohort Eric Perkins.

"Working for a locally owned company is a big part of what makes this appealing to me," said Turner, who worked for Cities 97 for 17 years, when the "adult" pop and rock outlet became a part of the Clear Channel chain. Turner was let go from his Cities morning duties in March and given a sales job in the company -- "a pretty joyless experience, but I was surrounded by some really good people," he said. In his new time slot (noon to 3 p.m. weekdays), he hopes to host on-air chats with local figures from the food, theater and music scenes who often joined him at Cities.

Like Perkins, Sarigianopoulos will continue her weekend anchoring and reporting duties at KARE-11 while carrying the K-TWIN morning shift (5:30 to 10 a.m. weekdays). She and Perkins also will be joined by a third co-host with more radio experience, Cane Peterson, a local native who has been working with Sirius XM and K-ROCK in New York.

PSY meets POTUS President Obama and his family saw "Gangnam Style" rapper PSY perform at a charity concert Sunday night, days after the South Korean pop star and Internet sensation apologized for a song in 2004 that called for killing "Yankees" in Iraq. PSY, 34, said he deeply regrets the "inflammatory and inappropriate language" that he used, and he said it was part of a "deeply emotional" reaction to the U.S.-led invasion of Iraq. The concert, called Christmas in Washington, which was filmed to be broadcast on TNT Dec. 21, raises money for the Children's National Medical Center in Washington. It was the fourth time the Obama family has attended the benefit.
