The National Intercollegiate Band (NIB) is a concert band, sponsored by honorary band fraternity and sorority Kappa Kappa Psi and Tau Beta Sigma, that performs every two years at the national convention of the two organizations. Organized in 1947, the NIB is the oldest national intercollegiate band in the United States, and is open to all collegiate band members regardless of membership in Kappa Kappa Psi or Tau Beta Sigma.
