This is a trend that is going on for a year or so: a Pop, Hip Hop or a Rock star thinks to himself: I need to re-invent myself as a sophisticated cat - I'll do a Jazz Album. I'll throw in a few standards, assemble a few musicians, and voila - A new and improved Star is born! And I'm not talking William Shatner here, I'm talking about "serious" singers.
Someone needs to tell these guys that Jazz isn't only about singing with a real drum kit instead of a machine and doing some standards.
