EPMD's reunion album Back in Business may not be entirely successful, but it's far from being an embarrassment.remain strong if unexceptional rappers, but the true news is in the music. Much of Back in Business captures the wild spirit of EPMD's classic late-'80s albums, complete with dense layers of sounds, samples, and funky beats. There's enough skill and invention in the production -- and just enough energy in the rapping -- to make Back in Business a welcome comeback.
