Jazz vocalist Gretchen Parlato contributed to Marcus Miller's latest album "Renaissance".
Gretchen Parlato is the daughter of Dave Parlato, the bass player that toured with Zappa Grand and Petit Wazoo Orchestra.
"Renaissance" includes a composition entitled "Mr.Clean". It's a funky jazz tune, not to be confused with the Zappa-penned tune.
