The venerable old Faye Spanos Concert Hall hosts jazz and other musical features on a regular basis. Tickets can be purchased on-line. Check out the University of the Pacific website or the Stockton, CA website. Dave Brubeck graduated from UOP and left a multi-million dollar endowment to the university, so expect seasonal jazz concerts that feature his music, if not him. I've also seen Winton Marsalis and band in concert here. Since this is not a large hall, the venue is an excellent place compared to similar productions in the San Francisco Bay Area, and the parking is free and easy to find.
Dress Code: No requirements are made, but typically locals will dress up for a formal jazz occasion. Young jazz fans rarely dress up though.
The day of the week has changed from year to year, but the summer concert series is always on a week evening, usually on a Wednesday or Thursday night, starting at 6pm. This summer marks the 55th year of doing this free concert picnic in Victory Park. Although alcoholic beverages are technically illegal, this seems to be overlooked as the upscale audience brings plenty of wine and food to the oak studded park. Victory Park is also the location of the Haggin Museum, so it's possible to combine an afternoon visit at this above average regional museum, and then spread out the picnic blanket for a free concert. The pictures so the venue. Usually the music style is jazz, but pop-rock and salsa are also common themes. See the website for the calendar and more details.
Across from Weber point and within walking distance of Howard Johnson Express Inn, the downtown multiplex cinema is new and inviting. There are several restaurants around it, and the 16 separate theatres are well designed for viewing and hearing the latest film releases. A walk around the fountains and end of the waterfront before or after the movie is pleasant enough. It's a good place to bring the kids, as the city police have a good presence in the area at night.
Dress Code: None, that I know of.
Nightclubs in Stockton are unfortunately few in number. However, recently the Waterfront Warehouse has hosted weekend Salsa and Merengue dancing. Lessons begin at 8pm, and at 9pm the savy and sophisticated dancing fans appear. It's right on the waterfront, so a drink outside between sets is possible. The old building itself is worth a look over.
Dress Code: Ballroom dancing crowds generally dress well, but there's not a dress code here.
