Boyz II Men

Boyz II Men are the most commercially successful R&B group of all time. They are an American vocal harmony group from Philadelphia, Pennsylvania, best known for emotional ballads and a cappella harmonies. They are currently a trio composed of baritone Nathan Morris alongside tenors Wanya Morris and Shawn Stockman. They are among the music industry's elite with regard to time spent at number one in Billboard history with 50 cumulative weeks, ranking sixth behind Drake, the Beatles, Rihanna, Elvis Presley and Carey.
During the 1990s, Boyz II Men gained international success. This began with the release of top 5 singles "Motownphilly" and "It's So Hard to Say Goodbye to Yesterday" in 1991, followed by the number one single "End of the Road" in 1992, which reached the top of charts worldwide. They sold ludicrous numbers of records and were involved in three of the longest-running number one pop singles in history, and they did it as a unit of equals.
