A friend recently shared a great filmmaker resource @ http://www.mobygratis.com.
Do you like Moby’s music? Do you want free music to use in your non-commercial work? Do you like using filmmaker resources that can connect you to others in ‘the industry’? (Yes, yes and yes.)
mobygratis is a resource for independent and non-profit filmmakers, film students, and anyone in need of free music for their independent, non-profit film, video, or short. Moby has made a selection of over 150 tracks from his huge catalog of music available to license for free, via a simple online application system.
To begin just create a new account, browse the catalog and fill in your application for the tracks you would like to use. You should receive a response to your application within 24 hours.
