NEW YORK (AP) — A coalition of musicians that has protested the Recording Academy's decision to drop 31 categories from the Grammy Awards is stepping up the pressure, calling for a boycott of the Grammys' telecast partner, CBS, and hiring a lawyer to explore legal action. "We will ask people to stop watching CBS, boycott their sponsors and then write them," said Bobby Sanabria, a Grammy-nominated Latin jazz musician and the leader of the coalition, in an interview Wednesday night. "We're at a critical juncture." The changes have drawn complaints from the likes of Herbie Hancock, Paul Simon and Bill Cosby. They also have gotten attention from organizations like the National Institute of Latino Policy, which issued a statement Thursday in support of Sanabria's coalition. Sanabria has claimed the reductions unfairly target ethnic music and called the Academy's decision racist.
