Freebie of the week: Some people keep saying jazz music is dead, but there are a lot of signs to the contrary. One hundred and nine years after its birth in New Orleans, the music is still with us, and appreciated by everyone from Boomers to Gen-Zers. One need look no further than the SFJazz Center and its lineup of concerts to see that the Bay Area in particular still has an appetite for jazz. And when it comes to jazz on radio and streaming sites, the Bay Area is likewise well-served by the San Mateo College station KCSM-FM 91.1, which began broadcasting in 1964. On Saturday, the station hosts its annual Jazz on the Hill free concert from 11 a.m. to 6 p.m. in front of the College of San Mateo library and theaters, 1700 W. Hillsdale Blvd., San Mateo. Performers include clarinetist Nathan Tokunaga; the beloved local vocal duo Tuck and Patti; Roger Glenn Latin Jazz Ensemble with guitarist Ray Obiedo; Miles Smiles, a Miles Davis tribune featuring Essiet Essiet, David Sanchez, Eddie Henderson and Akira Tana; and saxophonist-singer-songwriter Vanessa Collier. There is a family-friendly lineup on a separate Youth Stage, and plenty of food and drink will be available. More information is available at kcsm.org.ย

What about Bob:ย Technically, Bob Ross was a painter. Butย toย anyone of a certain age who spent any time watching PBS on TV,ย heย remainsย a pop cultural icon and phenomenon. To some, theย manย and his softly voiced painting tutorials, which still air on some PBS stations today, were an invitation into a quiet, gentle world without judgment. To others, he was something ofย a goofyย return to a long-gone era in which people valued simple, cheesy art and TV. Some viewers and beginner-painters valued his bare-bones instructions on how to create unchallenging landscape portraits, whileย others undoubtedly enjoyed Rossย (who learned to paint when he was in the militaryย before PBS started airing his classes in the early 1980s)ย and hisย lessons for their snark value. Folks in that last groupย likelyย willย not be on hand on Friday whenย WorkshopSFย hostsย a Bobย Rossย Paintย Along. Technically, the event is intended as a way for folks to get acquainted with the training facility at 1310 Haight St. in San Franciscoย and the various classes offeredย there.ย From 7ย toย 10 p.m.,ย guests mayย do all that and paint along as a Bob Ross segment is shown on a large screen. ย Fridayโs session is free, and youย donโtย need to bring any supplies. More information is atย workshopsf.org.ย

JJโs headlining gig: Drummer, percussionist, educator and band leader Josh Jones is known throughout the Bay Area music community for his sterling musicianship, often as a collaborator with such artists as Omar Sosa, Steve Coleman, Yosvany Terry, Jacqui Naylor, Taj Mahal, Bob Weir and Larry Coryell. His decades-long history on the local scene launched with his involvement with the acclaimed Berkeley High School jazz band, which included stints with such influential hip-hop artists as Tupac Shakur and the Digital Underground. This weekend, he steps into the spotlight at the Jazzschool in Berkeley, performing from 8 to 9:30 p.m. Saturday with his Latin Quintet, which also includes flutist Chloe Scott Jones, Danny Lubin-Laden on trombone, keyboardist Erick Peralta, and bassist Sadie Scott Jones (who happens to be the bandleaderโs daughter, not to mention a student at Jazzschool). The AfroCuban setlist will touch on works by luminaries Eddie Palmieri, Ray Barretto, Marco and many others. Tickets for Saturdayโs show are $26.39 ($16.21 for youths); go to jazzschool.org.

Cheap seats to a great opera: San Francisco Operaโs current production of Rossini’s frothy, frolicky โThe Barber of Sevilleโ has already begun its run, garnering rave reviews in particular for its opening night Rosina, sung by Russian mezzo-soprano Maria Kataeva in her American debut. And you can see her, too, from the comfort of your own home if you pop a mere $25 for the Friday night production that will become available on livestream for a fullย 48 hoursย beginning at 10 a.m. on Sunday. Cast alongside her in the title role as the clever, scheming barber Figaro is American baritone Joshua Hopkins, with South African tenor Levy Sekgapane as the lovestruck aristocrat Count Almaviva and baritone Renato Girolami as the overprotective guardian Dr. Bartolo. The opera is double cast, so some subsequent performances feature alternate cast members Hongni Wu, Justin Austin, Jack Swanson and Patrick Carfizzi in those same principal roles. But the glorious music, conducted by Benjamin Manis, remains the same throughout. Friday nightโs live performance in War Memorial Opera House begins at 7:30 p.m. Tickets for it and the subsequent performances, running through June 21, range from $29 through $447, available at sfopera.com. Check that website also for info on a special โEncounterโ performance of Act 1 on June 17 that will be followed by a lobby party that will immerse the audience into the comic world of the opera.ย

A musical nod to FIFA: Symphony San Jose, fully aware that the World Cup is hosting some events in Santa Clara County this month, closes out its season this weekend with a program that presents important works by great international composers. Denmarkโs Carl Nielsenโs โHelios Overture,โ an homage to the myth of the god of the sun, leads things off, with conductor Carlos Vieu at the podium. Vieuโs fellow countryman, Argentinian composer Alberto Ginastera, comes next with a highly unusual work, his 1956 Harp Concerto, which brought the instrument out of the domain of the angels and placed it squarely on center stage. The guest soloist is Katherine Siochi, principal harpist of the San Francisco Symphony, who will be demonstrating her skills with what is widely considered to be the biggest test of them for her instrument. Russian composer Dmitri Shostakovichโs mighty Symphony No. 5, a fist in the face of the oppressive Stalinist regime, closes out the program, which takes place at 7:30 p.m. Saturday and 2:30 p.m. Sunday at the California Theatre in downtown San Jose. Find tickets, $24-$121.50, at symphonysanjose.org. Following Saturday nightโs concert, there will be an โAfterglow: Cocktails and Conversationโ no-host gathering in the nearby Hilton Hotelโs Ahi Bar, featuring conductor Vieu, soloist Siochi and Symphony San Jose musicians. ย ย ย
