As a technical vocalist, Whitney Houston has few equals, but as advised, it is the use of the technique that betrayed her.
Her vocals were always a triumph of technique over feeling, of power over emotion.
The finest example of her lethal overkill is the gear change in I Will Always Love You – not present in either the original from Dolly Parton, or what is in my view the finest version, from Linda Ronstadt. Where Houston foghorns, apparently equating emotion with volume, Ronstadt’s voice weeps out of the speakers with barely withheld anguish. It is after all one of the greatest ‘lost love’ songs ever written, so to warble and trill and shriek all over it is to trample on the feeling and emotion it is deigned to communicate.
