The 5th Dimension

The 5th Dimension is an American vocal group. Its music encompasses sunshine pop, pop soul, and psychedelic soul. The band was an important crossover music act of the 1960s and 1970s, although both praised and derided for their particular musical approach and mass appeal. During the original group's heyday, they were twice invited to perform at the White House, and accepting those invitations was controversial during that era of social upheaval.
