Tony Galla

Also Friday night, the Tony Galla Band rocks the Valencia Jazz & Blues stage, on the street outside the Hyatt Regency off McBean Parkway. Galla’s a veteran blues and rock singer-songwriter-guitarist, a Jimi Hendrix protégé, no less. He’s a regular on the blues and Italian festival circuits, and has a ton of movie, TV and commercial credits. Showtime for Tony Galla is 7 p.m., and admission is free.

Last Saturday night’s Concert in the Park got rained out, but headliner Marie Wise-Hawkins and her band have been rescheduled for Saturday, Aug. 15, at 6 p.m.

The three local Country Showdown finalists who were supposed to open for Marie – Kylie Mac, Suzanne Harper and Jarett James – will open this Saturday night for The PettyBreakers, the Tom Petty & The Heartbreakers tribute band.

Country Showdown judges will pick one of the three finalists to go on to next round of the national competition, at Knott’s Berry Farm on Aug. 8.

Showtime at Central Park is 6 p.m. Saturday, and it’s free for all ages.

Finally, The Grateful Dudes, the longest-running bluegrass band in Southern California, returns to Vincenzo’s Pizza on Lyons in Newhall on Saturday night. Dude Herb Pedersen says the chances are also really good for a special guest or two. In the past, that’s often meant Herb’s frequent touring partner, Chris Hillman, one of the founding members of The Byrds and the Desert Rose Band. Call (661) 259-6733 for more info.
