The star this weekend is once again Pasadena. Head to ArtNight on Friday and enjoy a free evening of art, music and entertainment. Twelve of Pasadena’s most prominent arts and cultural institutions will open their doors from 6 to 10 p.m. ArtNight also features pop-up galleries, paint-spewing army ducks and food trucks, including ice cream sandwich truck Cool Haus (try the balsamic fig & mascarpone ice cream with an oatmeal cookie, weird but delicious!). Free shuttles will loop the area throughout the evening with stops at each venue, and a bike tour is available as well. Show your valid Metro ticket or pass at participating venues and receive special discounts, including 10 percent off store merchandise at the Pasadena Museum of California Art or 10 percent off exhibition catalogs at the Armory Center for the Arts. (Metro Gold Line to Memorial Park Station, depending on which venue you’d like to visit first different buses will serve your needs, check Metro Trip Planner.)

If you’re into acoustic music, visit the Last Bookstore in downtown Los Angeles on Saturday. String Theory, an all day acoustic music event, starts at 11 a.m. The event features musicians and dancers who put on a unique show using invented instruments and large-scale performance installations. Over 30 artists and special guests will be taking the stage. (Metro Red Line to Pershing Square Station, walk east on 5th St. to Spring St. Metro Bus Lines 16, 55, 62 to 5th/Spring.)

Saturday is also the opening day of Folding Paper: The Infinite Possibilities of Origami, an exhibition at the Japanese American National Museum in Little Tokyo in downtown Los Angeles. Folding Paper showcases the history of origami and the relationship between origami and art, science and mathematics, and you’ll be able to do some paper folding yourself in the Activities Gallery. The free family festival is from 11 a.m. to 4 p.m., so bring your kids, have fun and learn. Takayuki Ishii, author of One Thousand Paper Cranes, will be there at 2 p.m. for a book signing. (Metro Gold Line to Little Tokyo/Arts District Station, Metro Rapid 730 to Temple/Alameda.)

The Pac-12 basketball tournament concludes this weekend at Staples Center. The semi-finals are tonight and the championship games will be held Saturday, with the women’s game at 11:30 a.m. and the men’s game at 3 p.m. Tickets can still be purchased online or at the box office. (Metro Red or Purple Line to 7th/Metro, Metro Blue Line to Pico Station, Metro Bus Line 81 to Figueroa/12th.)

Sunday is Daylight Savings Time, so don’t forget to turn your clocks forward one hour – and don’t miss Il Volo, a three-person teenage singing group (or if you prefer, the Italian Jonas Brothers). The teenage tenors will be performing at The Grove at 4 p.m. on Los Angeles’ Westside and will hold an autograph session afterward. While you’re there, you might as well have some dinner. There are plenty of dining choices at The Grove, or head over to the Farmers Market side. I personally recommend trying Singapore’s Banana Leaf. (Metro Bus Line 16 or 217 to Fairfax/3rd, Metro Bus Lines 14, 37 to Beverly/Curson.)
