The Lawrence Arts Center, 940 N.H., will hold a Brazilian-themed party to celebrate the release of “Favela de Rocinha, Brazil,” a photography book by Lawrence artists Sarah Stern and Gary Mark Smith, from 3:30 p.m. to 6 p.m. Saturday.

The book chronicles life in one of Brazil’s largest gang-controlled slums, before the slum was occupied by Brazilian troops in November 2011.

The launch party will feature a portfolio of the book’s images, as well as Brazilian music and delicacies. The book will also be on sale with all proceeds being donated to the Brazilian neighborhood to fund a session of free art classes for teenagers.
