For those looking for an authentic jazz club experience—rather than the cheesy dinner-club vibe that prevails at too many other spots around town—Smalls is a must. The cozy basement space feels like a speakeasy, or more specifically, one of those hole-in-the-wall NYC jazz haunts of yore over which fans routinely obsess. Best of all, the booking skews retro, yet not stubbornly so: You'll hear classic hardbop as well as more adventurous, contemporary-flavored approaches.
