Just out of curiosity, can you name a CD produced in the US by a composer paid by the government to compose?

No, but if really I wanted to find one I'd probably start by looking here: https://www.arts.gov/ and then continue looking at smaller and more local arts grants. Also I'm sure that at some point some part of the government has commissioned new music for some project or event, although it's quite possible that that music has never been released on a CD.

But again it's all down to how you draw the line. Are you asking if there are composers on the federal payroll or if a composer has ever won a government grant and uses the money for that grant to pay his rent while continuing to compose?
