Materials & Applications is a Los Angeles–based art and architecture exhibition space. M&A's exhibitions typically take the form of outdoor, public installations and one-to-one architecture. The organization is one of dozens of small non-profit artist run spaces that have been called "feral" in their relationship to larger, more established organizations and museums in Los Angeles. Jeremy Rosenberg, a Los Angeles based writer, has likened it to other "feral" artist-run organizations such as The Museum of Jurassic Technology, Center for Land Use Interpretation, and Echo Park Film Center.
