Making it in the music industry as a solo artist is hard enough but when there are two or more people in a group, tensions are bound to arise because mo’ money plus mo’ people equal mo’ problems. Although they made beautiful music together, these 15 popular rap and R&B groups just couldn’t set aside their differences in the long run.

Arrested Development

Afrocentric alternative hip-hop group Arrested Development became very popular in the early 90′s. Founded by Speech and his former best friend, DJ Headliner, along with Dionne Farris and spiritual leader Baba Oje, they are best known for their song “Everyday People.” In 1993 the group won Grammys for Best New Artist and Best Rap Performance. They were also tapped by Spike Lee to record a song for his “Malcolm X” biopic that same year. However, Arrested Development never eclipsed the success they had with their debut album. Their sophomore album was panned by critics and shortly after that the group broke up due to “creative differences.” The band patched things up four years later but things were never the same as they struggled to reclaim their popularity in the U.S. Today, the group continues to tour internationally and released their 10th album in 2012.

One Chris, two Chris: The boys of Kriss Kross

Whether you’re part of the industry or listening from the outside in, everyone knows how fickle mainstream music can be. One hit is hard enough to come by, let alone an actual lasting and flourishing career. Hence the change up of our favorite R&B artists from lovelorn crooners to the newest school of techno babies (See: “DJ’s Got Us Falling in Love,” “Yeah 3x”. ) That’s why you can’t put a face to those early morning/late night radio jams that you barely remember the lyrics to: they’ve been diagnosed with the one-hit wonder syndrome.  Or in other cases, the fate of, “that’s that one song.” And while there’s nothing wrong with having a short career (better a little one than hustling mixtapes forever,) it does suck to be remembered as “that guy” or “‘ol girl.” So if you’ve been wondering who made some of your favorite songs from the ‘90s and up, or just if anyone else cares where they are, this list is for you.
