Add a new ‘post style’ page to blog

Hi, i am wondering if its possible to add a new page to my blog that appears in the menu at the top with home etc… and be able to post to that page seperately from the main post page?

the purpose of which would be to have seperate menus that people can navigate to for different topics; say – ‘gig reviews’ and ‘album reviews’ for instance. i would want to update each page regularly and have them both contribute to the archive section but be kept seperate fron the main blog.

I’ve tried adding a new page but can only add static content to this. Is the function i’ve described possible? or am i missing something obvious?
