The Hooked on...syndrome is apparently catching, and Brewer, who has become a stylish interpreter of pop music after the silliness of her early career, has got the disease. Her I Dig album includes excerpts from 35 songs, grouped according to the bands that made them famous (Jimmy and Tommy Dorsey, Glenn Miller, Benny Goodman and two sets of miscellaneous medleys). The backup band includes such splendid musicians as trombonist Urbie Green and drummer Grady Tate. Brewer sounds vivacious and interested. But condensed music is inevitably frustrating and maddening. There ought to be a law against this sort of thing. It's especially annoying in comparison to Brewer's other current release, with the venerable jazz violinist Grappelli. Included in that LP are a bright version of the Willie Nelson title tune, a thoughtful As Time Goes By and the delightful Kay Thompson song I Love a Violin, written as a friendly retort to Irving Berlin's I Love a Piano. To quote the old Brewer hit, this album is full of music, music, music.
