The electronic press kit is a powerful promotional tool for your band - consider it your musical resume. It will catalogue any of your material, media, press, calendar dates; anything you think you'd want promoters or venues to see. The EPK can hold as many photos, songs, and videos as you want. It can link to all your social media profiles to showcase your fanbase to the reviewing promoters, and it can provide powerful feedback as you send the EPK out to promoters, venues, and other contacts about how your band is viewed and where and when you're getting booked.
