Too much work and not enough nightlife? Looking to kick-start your weekend? Rod Piazza & the Mighty Flyers are a great bet, especially if you’re into blues harmonica. Although Piazza’s schedule is a bit hectic these days, he still manages to work in a show or two in the Sacramento Valley each year. His new CD, For the Chosen Who, hearkens back to his humble beginnings while updating his already vibrant live show. For blues aficionados, it gets no better. Swing and shake to the sounds of the Mighty Flyers this Friday at the Powerhouse Pub, located at 614 Sutter Street in Folsom. The show starts at 9:30 p.m., and tickets are $10.
