The Brief Beyoncé brings her Cowboy Carter tour to Northwest Stadium in D.C. on Friday, July 4. Metro rides are free after 5 p.m., and Metrorail runs until 2 a.m. under new systemwide hours. Beyoncé once paid $100,000 to extend Metro hours – but new changes may make that unnecessary. This Fourth of July, Cowboy Carter hits the capital. Cowboy Carter, released earlier this year, is a cultural declaration, rooted in American traditions yet radically reshaped by her artistry.
