Boyz II Men

Formed at Philadelphia's High School for Creative and Performing Arts, the group polished tight a cappella harmonies before being signed to Motown.

Hits like "End of the Road," "I'll Make Love to You," and "One Sweet Day" with Mariah Carey shattered chart-longevity records during the 1990s.

They won four Grammy Awards and are among the best-selling R&B groups of all time, with several record-setting number-one runs.

Boyz II Men perfected the lush vocal-harmony ballad, becoming the most commercially successful R&B group of their era.
