Vijay Iyer is the kind of 21st century improvised music performer you can’t sum up in a blurb. His corpus demands something more formal—a CV, or a testimonial, something like that. I’m not teasing—Iyer is one of the finest examples of the new breed of musician, equally at home in the academy or the club, committed to an overarching vision that hews to no particular style. He’s done the trad thing, he’s done the jazz with electronics thing, he’s done all manner of unclassifiable in-between things. Most recently, Iyer, Arooj Aftab, and Shahzad Ismaily recorded Love in Exile, which made ripples outside of the typical jazz/improv circles; the three musicians played a sold-out show at the Cedar in October. For tonight’s performance, which was originally scheduled for November 2022, he’s performing with bassist Harish Raghavan and drummer Jeremy Dutton. (RACKET)
