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. During the 1990s, Boyz II Men found fame on Motown Records as a quartet including bass Michael McCary, who left the group in 2003.
Boyz II Men is 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. These achievements were enough to earn Boyz II Men recognition as Billboard magazine's biggest boy band during the period of 1987 to 2012.
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. In fact, their four-part harmonies blended so smoothly that most of the general public would be hard-pressed to name any of the group's individual members.
