I have come across stories of FB marketing success, but success in terms of projected & achieved 'likers'. They usually do not convert to ticket sales in a gig. There are a number of music promotion platforms other than FB, soundcloud.com, jamendo.com, which offer both free & paid services for artists & runs on your primary social networks for users & followers. But for projection & analysis of user stats a seperate campaign management app can help sort out issues which I do not know if exists or whether can be integrated with social network data.(I would love to know of such a tool for my brother's band too.)
