In the late 1960s, Richard and Karen Carpenter formed the brother-and-sister duo the Carpenters. Richard arranged the music and played the keyboard while his younger sister Karen sang vocals and played the drums. Together, the Carpenters are still the top-selling and top-charting brother-sister group of all time. Signing their first record deal as a duo in 1969, they rocked hundreds of shows through the ’70s, topping the charts in the U.S. and internationally. But one of their lives would be cut tragically short, ending the duo in 1983.
