April 21. The modern wunderkind of jazz, 13-year-old pianist Joey Alexander was six when he taught himself how to play. Since Wynton Marsalis invited him to play at Jazz at Lincoln Center in 2014, Alexander has performed for Herbie Hancock and presidents Bill Clinton and Barack Obama, won the Grand Prix at the 2013 Master-Jam Fest, and appeared at the 2015 Montreal and Newport Jazz festivals. Having received multiple Grammy nominations—the youngest musician ever to do so—Alexander, whose trio delivers this concert at the Woodstock Playhouse, struck number one on the Billboard charts in both the Traditional Jazz and Contemporary Jazz categories. But despite his young age, to the leading jazz authorities Alexander is no mere novelty act; Down Beat gushed, "If the word 'genius' still means anything, it applies to this prodigy." 7:30pm. $40, $50, $60.
