The last time I saw the Crash Test Dummies, they were beginning to succumb to the polite sound of "adult alternative." You know, where all the pretty acoustic instruments turn interesting songs into boring mush? Too bad, because their first two albums were idiosyncratic affairs that deserved the critical praise heaped upon them. The debut, The Ghosts That Haunt Me, introduced singer Brad Roberts' disquietingly deep voice and the gentle, sardonic humor that characterizes their best songs. "Superman's Song" and a cover of the Replacements' "Androgynous" were the highlights. The follow-up was even better; God Shuffled His Feet turned into a major hit on the strength of "Mmm Mmm Mmm Mmm," and band seemed poised for great things. Subsequent records have been big disappointments, though, and the smart shopper will avoid them.
