Target Audience for my Magazine

For my magazine, I would like the target audience to be that of a mature age, but also still has fun at heart. Possibly a bit like the NME, but with more formality about it, so it appeals to a younger audience but also an older audience. Having interviews with new artists but also classic artists definitely opens a window for me to put my magazine out to a wide audience. I am thinking of going with a design like the music magazine "Clash" but having it jam packed inside with fresh new talents and classics, just like the NME. I think this mix between the two will work very well, with the "Clash" being quite formal and mature, and the NME being quite alternative and immature.
