Seeking CMS for Client

I am seeking a content management system solution for a client. I am primarily a designer and have only recently started studying CMSs.

Right now I am in preliminary stages trying to conceptualize in photoshop. I want to make sure I’m not trying to achieve something too difficult or maybe unnecessary. I’d like to know what CMS solutions there are that might be apt for my goals.

The client wants a couple of weblogs possible for themself and additional engineers at a recording studio. Also pages will load randomly selection images, or album production information (image of the cover and title), or random audio.

Any suggestions on how I might go about this? Any advice to prevent making this project as simple as possible? Any criticisms on the early example provided? Thanks.
