Jimmy Jam is best known for his work producing songs with R&B hitmakers Janet Jackson, Boyz II Men, Mariah Carey, Usher, George Michael, Chaka Khan and others. But before all that, he was a member of the band the Time, which opened for Prince in the early days of the Minneapolis Sound. He remembered Prince as a virtuoso and a workhorse.
