Query: A Cautionary Tale

This recording would be useful for singers planning to perform Brel, as a warning of what to avoid when singing these exquisite songs. Glibness and unnecessary flourish - no matter how talented the voice - as well as the attempt to put too much of a personal "stamp" on Brel, are deadly mistakes. The songs of Brel communicate beautifully for themselves if the singer is grounded in emotional directness and authenticity.
