Sultry sounds and groovy tunes are making their way back to San Jose this weekend for the 31st annual three-day San Jose Jazz festival. That’s right, Summer Fest is back — and bigger than organizers originally envisioned. Despite pandemic closures and hiccups, the jazz festival will have a six-stage show with more than 45 different artists with a wide range of styles that include R&B, blues, Latin, swing and of course, all kinds of jazz.
