For the second summer in a row, Jazz at Lincoln Center returns to its roots with this regularly scheduled, rain-or-shine Jazz Underground Sunday concert series at The Underground at Jaffe Drive, located under Josie Robertson Plaza. Curated by the knowledgeable Jazz at Lincoln Center team, a handpicked selection of rising stars and venerable instrumentalists will congregate to delight audiences at this pop-up bar and performance stage. Whether it’s in reference to the subterranean clubs where legendary performers have traditionally honed their chops or to the lingo of the knowingly hip in-crowd, the underground tradition in jazz is an important and lasting part of that music’s history.
