The TBA Festival ain’t just for highfalutin grownups; tiny tba is where tykes get their chance to be artsy. (Or just messy, depending on how much of a critic you are.) Resident DJs from Greasy Kid Stuff, the Portland-based radio show for kids, will be on hand with tunes for shaking those Pampers. There’ll be face painting, chalk drawings, songs by Elizabeth Mitchell, crying, napping, a screening by Indiekid Films, balloons, bubbles, aerobics by Anna Oxygen, maybe some more crying, and a performance by dance troupe Hot Little Hands. Oh, and reportedly? Lots and lots of MILFs.
