From the FOUND collection.

8 p.m., ACAC Building. $5.


Eight years ago Davy Rothbart found a note on his car, meant for someone else, that began with, “Mario, I fucking hate you … whys your care HERE at HER place??” and ended with, “PS Page me later.” That find led Rothbart to launch FOUND magazine, an annual-ish collection of found love letters, poetry on napkins, to-do lists — anything discovered by a stranger that offers an insight into someone else’s life. Rothbart’s project lives on largely because, as he says, it’s evolved into a sort of community project, with 100-200 found things mailed to FOUND HQ (his parent’s house) per week. Earlier this month, Rothbart released his third FOUND book, “Requiem for a Paper Bag,” a collection of stories about found stuff from mostly hipster-ish celebrities, people like Andy Samberg, Miranda July and Chuck Klosterman. To celebrate, Rothbart and his brother Peter are on a 55-city cross-country tour, where they’re spreading the gospel of FOUND with readings of the latest and greatest that have landed in their mailbox and through Peter’s songs, which are based on FOUND notes.
