Last summer, Bay Area artists Sophia Wang and Lisa Rybovich Crallé created Heavy Breathing, a season-long series of critical theory and creative practice seminars that took the form of aerobics classes and were taught by local artists. Pretty simple. Now, they’re doing it again, but this time in collaboration with the Berkeley Art Museum and Pacific Film Archive (2155 Center St.). The series will kick off this Sunday with a session led by artist Stephanie Syjuco, in which participants will collectively transform modeling materials into sculptural commentaries on craft, quality, and capitalism. As the programmers put it: “‘Public Productions’ will utilize non-specialized skill sets and labor to produce vernacular versions of iconic objects, exploding the notion of specialized or standardized labor to open up a space of play, invention, and learning-as-you-go.” New sessions will be held monthly and are free with museum admission ($7–$12). “Public Productions” will take place from 2–3 p.m.
