Long stretches, salutes to artists etc (be they Muddy Waters, Beethoven, or genres etc.) I remember the short-lived (Radio) Waves magazine, late 70s, listed the orgies and no doubt
the WHRB program guides and websites do as well.
The online WHRB program guide covers April only but says the Spring Orgies begin May 1
What is a WHRB Orgy?

>>it is said that one Harvard student, then a staff member of WHRB, returned to the station after a particularly difficult exam and played all of Beethoven's nine symphonies consecutively to celebrate the end of a long, hard term of studying. The idea caught on, and soon the orgy concept was expanded to include live jazz, rock, hip-hop, blues, and even sports Orgies.
The Orgy® tradition lives on even today at WHRB. During the Reading and Exam Periods of Harvard College, WHRB presents marathon-style musical programs devoted to a single composer, performer, genre, or subject.
