Vijay Iyer and his wild new jazz combo Thums Up treated fans to a mind-widening rap/jazz/Sufi poetry concert on Sunday, Jan. 21, at SFJazz Center’s Miner Auditorium. “And now,” Iyer announced at the top of the set, “SFJazz presents something off the beaten path.” He wasn’t kidding. Sunday was the final concert of Iyer’s four-day run at SFJazz, where he has been serving as the venue’s resident artistic director since January 2017.
