The West Coast Musical Improv Festival (WCMIF) is produced by the Un-Scripted Theater Company®, which since 2002 has created smart, innovative, and entertaining improvised theater that delights audiences and advances the craft and art of improvisation. The WCMIF was launched to celebrate the rise of musical improv in the Bay Area and to invite seasoned troupes from around the country to share and play together! 

Un-Scripted Theater Company has staged over forty productions in a range of genres and styles: stage plays, musicals, narrative long-form, improv comedy, and theatrical experiments. It aims to expand the boundaries of improvised theater. The company performs in San Francisco and was named "Best Theater Company 2008" by the SF Bay Guardian.
