The thing about Anita Wardell is that she makes tricky stuff sound not just easy but natural. There are moments here, on well-known standards such as You're My Thrill and Without a Song, that could be harmonic and rhythmic minefields, but she sings them all with an airy grace. Her mutual understanding with Robin Aspland, that most lucid and inventive of pianists, is a constant delight. And when it comes to scat singing, for which she is famous, if this breakneck version of Frevo Em Maceio doesn't put a spark into your day, nothing will.
