If you're looking to get an authentic taste of swing dancing, you can do no better than Tuesday nights at the Verdi Club. The evening starts off with a half-hour intro into the basics of swing dancing, lead by Bay Area swing veteran Hep Jen. Then the Stompy Jones six-piece band takes the stage, pumping out infectious jump blues. Students from the classes offered before the dance fill the space, many decked out in the fashion of the era. A four-class package beginners and intermediates costs $65; drop-ins pay $20 per lesson. The place is welcoming and friendly: Everyone from the brand-spanking new beginner to your grandpa who still cuts a rug every Friday at the local community hall will feel at home dancing the night away.
