The "Bird-Prez Birthday Broadcast", a 72 hour (and some years longer) marathon celebrating Lester Young and Charlie Parker around their birthday anniversaries, August 27 and August 29, is a long standing tradition at WKCR, and it is among our listeners' favorites.
Here's a three hour set of mine from the 2021 edition, which includes an 80 minute long segment featuring recordings of Charlie Parker in unconventional large group settings (other than Bird With Strings"), and then samples of some other more standard Bird sessions, including a live set from his perch at the Royal Roost.
