WHAT : Who are the B-Side Artists? They’re not The Highwaymen. If anything, the streets these creatives keep to are a little farther off the beaten path — but you’ve probably seen the marks they’ve left behind. In recent years, the art of Swamburger, Chris “Tobar” Rodriguez, German Lemus and the rest of this collective have defined the underground scene in Orlando. “Sell Out” marks their fifth annual group show at CityArts Factory, adding new faces like Karen Russell and 15-year-old Halsi Helfrich to the fold. While you’re there, check out the works of B-Side member “Tr3″ Harris and 60 other artists decorating the decks in “Boarded Up: The Art of Skateboarding,” on view at CityArts and NV Lounge (27 Pine St., Orlando).
