Target Audience

This is Jo, she is 19 years old.  Jo likes to listen to Indie rock music. Jo would be the ideal reader for IR magazine.
At the weekend Jo likes to listen to go to gigs with her friends.
Jo likes obscure things that not many other people have heard of.
Jo's favourite colour is red and she often likes to change the colour of her hair.
Jo hate's pop music.
Jo is very much a fan of the outdoors and she likes to go camping.
Jo is in an indie rock band. She plays the guitar and sometimes she sings. This is a conventional reader of the audience group I am appealing to.  I would say the audience I am appealing to is mass rather than niche. 
Jo would be the ideal target audience for IR because she would be interested in the bands and news that is featured in the magazine.
