I am birthday shopping for someone who is a voracious reader but always stays one step ahead of me. When I buy something, he says "I've already read that."

So with that in mind, what are some of the VERY recent books released about music that I might want to consider? For example, what Motown subject matter has been released in the past few months?

Also he was an Olivia Newton-John fan, so is there anything new on her or a recommended biography?
