Boyz II Men is an American R&B vocal group best known for emotional ballads and acappella harmonies. This group is a trio, featuring baritone Nathan Morris alongside tenors Wanya Morris and Shawn Stockman. In the 1990s, Boyz II Men found fame on Motown Records as a quartet, but original member and bass singer Michael McCary left the group in 2003 due to health issues.
In the 1990s, Boyz II Men gained international celebrity behind unprecedented success on the pop charts. The group's first single to reach Number 1, 1992's "End of the Road" reached the top of charts across the globe. "End of the Road" would set a new record for longevity, staying at number 1 on the Billboard Hot 100 for 13 weeks, breaking a decades-old record held by Elvis Presley. Boyz II Men would exceed even that record later in the decade with hits "I'll Make Love to You" and "One Sweet Day" (with Mariah Carey), which each set new records for the longest period of time a single remained at number 1. As of 2012, "One Sweet Day" still holds the all-time record with 16 weeks at the top of the Hot 100. In short, Boyz II Men ranks at the top of the list three times – at the number one, three, and four spots – for the longest running Number 1 singles in Billboard history. Furthermore, when "On Bended Knee" took the number 1 spot away from "I'll Make Love To You," Boyz II Men became only the third artist ever (after The Beatles and Presley) to replace themselves at the top of the Billboard Hot 100. Boyz II Men are among a select group of artists that have held at the number one spot for at least 50 weeks cumulatively, placing them just fourth on that list behind Elvis Presley, The Beatles, and Mariah Carey. These achievements were enough to earn Boyz II Men recognition as Billboard Magazine′s fourth most successful musical group of the 1990s.
