Crash Test Dummies
Then: Crash Test Dummies broke big in the Canadian music scene in 1991 with their debut single "Superman's Song," but most Americans first heard of them two years later when "Mmm Mmm Mmm Mmm" went into heavy rotation on MTV. The song was instantly memorable, if only for the extremely low singing voice of lead singer Brad Roberts. Plus, you don't hear a lot of bass-baritone singers fronting rock bands, and you don't hear a lot of songs with a one-word gibberish chorus.
The song (produced by Talking Heads guitarist Jerry Harrison) is also really, really weird. Sample lyric: "Once there was this kid who got into an accident and couldn't come to school/But when he finally came back his hair had turned from black into bright white." Basically, it's a song about three kids: One is in a car accident that turns his hair white, another is a girl with birthmarks all over her body who's ashamed to change in front of her friends and the last is a boy whose family is involved with a fundamentalist church that makes worshippers fall to the floor and shake. It shot to Number Four on the Hot 100.
Now: Crash Test Dummies had One-Hit Wonder written all over them. They even named themselves after something that's only good for a single use. In fairness, they scored hits in Canada until the late Nineties. But in America they were finished as soon as "Mmm Mmm Mmm Mmm" fell off the charts. It was somewhat of a novelty song, and novelty songs are notoriously hard to follow up. The band never gave up, though. They released their most recent album in 2010, though they had to cancel a bunch of tour dates because Roberts has back problems caused by a herniated disk. Being a Crash Test Dummy isn't easy.
