MC Hammer is bluegrass??!!

Looks like the official lineup of this year's Hardly Strictly Bluegrass has been announced. http://www.strictlybluegrass.com/ I'm pretty stoked about some of the non-strictly bluegrass artists performing this year, which include Odetta, Will Oldham, Elvis Costello, Nick Lowe, Iron & Wine and what...MC Hammer? Not sure whether or not this is a joke, but Hammer getting down to some banjo sounds AMAZING.
