EMF hit #1 this week in 1991 on the Billboard Hot 100 with “Unbelievable,” the rare dance song to reach that height (and probably the only song of any stripe to sample comedian Andrew “Dice” Clay). The band, whose name officially stands for Epsom Mad Funkers (several curse-infused variations exist), formed in Forest of Dean, Gloucestershire, England in 1989.

You might think, as I did, that EMF were one-hit wonders, but isn’t true. “Lies,” the follow-up to “Unbelievable,” hit #18. That track featured a voice sample of Mark Chapman, the man who shot and killed John Lennon; that didn’t sit well with Lennon’s widow, Yoko Ono, and the offending bit was ultimately removed.

But back to the song that everyone knows. “Unbelievable” has continued to pay off for EMF, as the track has found a second life in TV commercials. In the last few years, it’s been used to sell Hallmark cards and Kraft cheese (“Crumbelievable”), which has helped to further cement this dance-rock anthem’s place in pop culture. But nothing beats the original:

Of course, it’s not unusual for another artist to take a popular song and give it his or her own twist. “Unbelievable” became a staple of Tom Jones’ live gigs. Check out Tom chatting with EMF about his attraction to the song.

Though EMF has continued to perform and record over the years, the band has taken long hiatuses in between doing so (they lost their bassist to a drug overdose in 2002). They’ve played a couple of dates this year and it’s been reported that the band is working on its first set of new songs since 1995’s Cha Cha Cha.
