Who are my target audience?

Well I originally chose this indie rock band as I am into this sort of music, therefore my target audience would be young students (about 17-20's) like myself, my band most represents paramore meets arctic monkeys, therefore appeals to girls and boys that are into the whole indie fashion and genre. The band would no doubt play in a venue like Rock City (in Nottingham) not as "big" as bands such as Kasbian and Kings Of Leon, more in their early days!
