In the liner notes to 'When I Look In Your Eyes,' Jazz vocalist Amy London’s 2007 debut CD as a band leader, radio host and author Sheila Anderson cites London among an "elite group of female stylists, including Sarah Vaughn, Carmen McRae, Nina Simone and Shirley Horn." High praise indeed for a singer whose voice has been described by acclaimed pianist Fred Hersch as "a beautiful and expressive vocal instrument." Like Hersch, London has Cincinnati roots, so her upcoming appearance here will be a homecoming of sorts. London performs Friday and Saturday at Blue Wisp Jazz Club.
