The final concert of the season by Lander University’s Jazz Ensemble on Thursday, April 14, will be a study in contrasts. Brassy numbers like Kris Berg’s “Fowl Play,” “Cold Duck Time,” by Eddie Harris and Joe Garland’s “Leap Frog” will alternate with more introspective pieces, like “Quiet Nights of Quiet Stars,” by Brazilian composer Antonio Carlos Jobim, “The Creole Love Song,” by jazz great Duke Ellington, and “Django,” John Lewis’s tribute to jazz guitarist Django Reinhardt.
