Editor's note

Last month, Weezer released its “Teal Album,” an LP that consists entirely of cover songs. One of the tracks, a cover of Toto’s “Africa,” has given the band its first chart-topping hit in 15 years. Colorado College’s Ryan Raul Bañagale explores the history of cover songs – the forms they take, their appeal and when the practice veers into exploitation and appropriation.

Since its emergence in the 1830s in the taverns and on the theater stages of New York and other northern cities, blackface has involved the vicious ridiculing of people of African descent. Blackface offered the perfect entertainment for a slave nation and then, after the Civil War, a society built on racial segregation, writes Michael Millner of the University of Massachusetts Lowell. But its use continued well into the late 20th century, a fact that a Virginia governor's yearbook reminded Americans of in recent weeks.

Parents have to create the right conditions for children to develop their talents. University of Nebraska – Lincoln educational psychologist Kenneth A. Kiewra interviewed parents and coaches of young people who excelled in pursuits as diverse as chess and tennis, to find out what those conditions are.
