One of the most important vocal groups in jazz history, The Four Freshmen pioneered a revolutionary new style of close-harmony vocals that set the stage for bands like the Beach Boys, the Hi-Los and Manhattan Transfer. Popular through the ‘50’s and ‘60’s, and enjoying a come-back in recent years, they are known for hit singles such as “It’s a Blue World,” “Mood Indigo,” “Day by Day” and “Graduation Day.”
