Genre: R&B
Boyz II Men is a Grammy Award-winning African-American Rhythm&Blues/soul singing group from Philadelphia, Pennsylvania. Initiated during 1988 as a quintet which originally included Marc Nelson, Boyz II Men found fame as a quartet, with members Nathan Morris, Michael McCary, Shawn Stockman, and Wanya Morris, on Motown Records during the early 1990s. Nelson left the group before their first recording to pursue a solo career.
Based on sales, Boyz II Men is the most successful R&B male vocal group of all time. They recorded five #1 R&B successes between 1992 and 1997 and have sold more than 60 million albums. Three of its #1 hits, "End of the Road", "I'll Make Love to You", and "One Sweet Day" (with Mariah Carey), set and exceeded records for the longest period of time a single remained scored at #1 on the Billboard Hot 100; "One Sweet Day" still holds the record. Although "On Bended Knee" did not exceed any records, it was still a very popular song that reached #1 and made Boyz II Men the second artist (behind The Beatles) to replace themselves at the number one rating of the Billboard Hot 100.
