The art of the cabaret song performance  is the basis of The Cabaret Room.

There are some excellent examples  of  that in this months podcast from
singer Curtis Stigers whose appearance at Ronnie Scotts Jazz Club has been
sold out for some time.  Roseanna Vitro a wonderful and expressive jazz
performer sings in the bijou Mezzrow club in New York, while in the Piano Room a first time appearance from Scottish pianist Brian Kellock is a thrill 
and Claire Martin and her late partner Richard Rodney Bennett leave a possible hint of something that might happen later ?
