The Infinite Loop will throw a party at Soul Camp March 11 to release its debut EP, First Contact, launching its campaign to become D.C.’s foremost independent hiphop group. On “Nation’s Cap,” these MCs insist that the District “ain’t never been whack” and support that claim with low-down dirty bass changes and a bouncy Southern-fried second verse. In an act of wisdom unusual among underground rappers, the Loop has dedicated the last half of Contact to material fit for radio: “Earth Girl,” a soothing ode to “honeys,” is nearly as lovable as the Roots’ current commercial hit, “You Got Me.” The Loop also has the professional charisma and dynamic stage presence that major labels like.—Neil Drumming
