Which R&B group released the 1991 album Cooleyhighharmony?

The R&B group that released the 1991 album Cooleyhighharmony is Boyz II Men.

Cooleyhighharmony is Boyz II Men’s debut studio album, released by Motown Records on April 30, 1991. Its title pays tribute to Cooley Vocational High School in Chicago, where group member Nathan Morris attended. The album helped introduce the group’s polished vocal harmonies and blend of contemporary R&B, soul, and new jack swing.

The album’s best-known early singles included “Motownphilly” and “It’s So Hard to Say Goodbye to Yesterday.” Cooleyhighharmony initially entered the Billboard 200 at number 58 but eventually climbed to number three as the group’s popularity grew.

A frequent mix-up is assuming the album came from Jodeci, Silk, or Shai, other prominent male R&B groups from the same period. Those acts also shaped early-1990s vocal R&B, but Cooleyhighharmony is specifically Boyz II Men’s debut. The group later became especially known for ballads such as “End of the Road” and “I’ll Make Love to You.”
