Los Angeles
– Aug. 2 (Tues.) Yes and Styx. Two of the classic rock franchises — still going strong — team up for a display of some of the archetypal music of the ’70s and ’80s. The Greek Theatre. (323) 665-5857.

– Aug. 3 – 7. (Wed. – Sun.) John Pizzarelli and Jessica Molasky. Collectively and individually, the married team of singer/guitarist Pizzarelli and vocalist Molasky make for one of the jazz world’s most entertaining acts. Capable of generating the humor of the great husband and wife teams of the past, they also bring a rare blend of musicality to their singing and playing that is uniquely their own. Catalina Bar & Grill. (323) 466-2210.
– Aug. 3 – 7. (Wed. – Sun.) Clarinet Fest 2011. Everything you ever wanted to know about the clarinet, or hear about the clarinet will undoubtedly take place in this large assemblage of programs and seminars. Clarinet ensembles of every stripe will perform. Among the many highlights are performances on Sunday by the Eddie Daniels Quintet and the Clare Fischer Clarinet Choir. But there are numerous others, from many other parts of the world. Clarinet Fest 2011 in the Valley Performing Arts Center at CalState Northridge.
– Aug. 4. (Thurs.) Ron Kalina’s Birthday Bash. Versatil jazz harmonica player Kalina — who also plays piano, leads a celebratory evening of music to remember. He’s backed by vibist Gino Antonachi, bassist Pat Senatore and drummer Ryan Doyle. Vibrato Jazz Grill…etc. (310) 474-9400.
– Aug. 4. (Thurs.) Hippiefest. The annual installment of music from the peace, love and rock ‘n’ roll generation returns for the sixth time.

– Aug. 4. (Thurs.) Yemen Blues. The Skirball’s always entertaining, free Sunset Concerts continue with an appearance by a band that produces a steaming gumbo of music spiced with elements of jazz, blues, Jewish melodies and African grooves. Don’t plan to sit still when this band starts to kick it. Skirball Center. (310) 440-4500.

– Aug. 6. (Sat.) Annie Sellick. Her bold, assertive style, blended with occasional touches of vulnerability make Sellick an appealing singer — one whose work warrants a wider hearing than she seems to be receiving. Steamers. (714) 871-8800.
– Aug. 6. (Sat.) Judy Wexler. Critically praised jazz vocalist Wexler celebrates the release of her third CD, Under A Painted Sky, backed by some of the stellar players on the album — pianist/arranger Alan Pasqua, guitarist Larry Koonse, saxophonist Bob Sheppard, bassist Darek Oles and drummer Steve Hass. Vitello’s. (818) 769-0905.
San Francisco
– Aug 5 – 7. (Fri. – Sun.) Los Van Van. It’s been more than four decades since Juan Formell organized the fusion Cuban band Los Van Van. Expanding on the traditional charanga style, instrumentally as well as the choice of material, he created a band that continues to provide musical thrills at every performance. Yoshis Oakland. (510) 238-9200.

– Aug. 7. (Sun.) Turtle Island String Quartet. When the Turtle Islanders first posited the notion that the members of a string quartet — if they possessed the right blend of talent and imagination — could play with the creative liberation of a jazz group, it seemed a radical idea. (Despite the fact that their goal also included reviving the improvisation that had been for centuries a fundamental part of classical music as well.) But they’ve made their case convincingly, winning Grammy awards and opening an expressive pathway that more ensembles should explore. Yoshi’s San Francisco. (415) 655-5600.
Seattle
Aug. 4 – 7. (Thurs. – Sun.) Bill Frisell. Ever on the trail of another musical idea, Frisell’s Beautiful Dreamers features violinst Eyvind Kang and drummer Rudy Royston in a challenging, but potentially productive musical setting. Jazz Alley. (206) 441-9729.
Chicago

Aug. 4 – 7. (Thurs. – Sun.) Charles McPherson. It’ll be an evening of Charlie Parker revisited when McPherson steps on stage. But not in an imitative sense. McPherson’s connection with Parker is inspirational, and the results are always musically compelling. Jazz Showcase. (312) 360-0234.
New York
-Aug. 2 – 4. (Tues. – Thurs.) McCoy Tyner expands his usual trio format to a quintet featuring the two saxophone front line tenorist Ravi Coltrane and alto Gary Bartz. And it’s hard to imagine a more compatible assemblage of world class players. Birdland. (212) 581-3080.
– Aug. 3. (Wed.) The Center for Improvisational Music. Trumpeter Ralph Alessi, alto saxophonist Tim Berne, pianist Kris Davis, bassist Michael Formanek and drummer Gerald Cleaver — present and former faculty members — celebrate the 10th anniversary of the School for Improvised Music’s pioneering work in the exploration of the art of improvisation. Cornelia St. Cafe. (212) 989-9319.
London

– Aug. 4 (Thurs.) Claire Martin. She’s often described as England’s best jazz singer, which may well be true. But Martin is more than that — a versatile performer with the capacity to find the inner life of whatever she sings in whatever style. She appears with the Richard Rodney Bennett/Bobby Wellins Quartet. Ronnie Scott’s. 020 7439 0747.
Tokyo
– Aug. 2 – 5. (Tues. – Fri.) Joyce with special guest Sergio Santos. Singer/songwriter Joyce — who now occasionally also uses her last name, Moreno, has been a highly visible figure in Brazilian music since the MPB era. Still an engaging performer, she appears here with the gifted guitarist/songwriter/singer Santos, whose talents are still too little known in the U.S. The Blue Note Tokyo. 03-5485-0088.
