George Avakian is the jazz producer of Columbia Records.
The statement lets us know George Avakian was a Columbia Records jazz producer as of 1960. We do not know if he still is, as the statement gives no information about what George Avakain "is" doing in 2019. The statement was probably hard to evaluate because it required recognizing subtle differences in past vs present.
