Research: Invitations and business cards.

I am looking at invitations for my potential launch event, I would like to create an invitation that is visually pleasing and interactive.

I could create an invitation specifically related to music and music records:

I could interactively produce an invitation that takes a picture, or plays new music to the clients:

Or a balloon idea is a nice small gesture:

This is a simple record invitation in a sleeve:

I have also looked at business cards as I would like to produce my own business card that professionally promotes my agency to all of my clients and potential customers.

I like the imprinting of the text on this one as well as the neon lining:

This is a really clever idea and its creative, however you may not be able to get much information on this:

This holographic design is contemporary and it would attract the right clients for me:

A simple but effective idea, the white is great to appeal to both genders and I like the cut out shapes:

A business card that you can eat:

Overall, I would like to produce an invitation that is different, so maybe looking into our hearing senses would be an interesting route? Then for my business cards I would like to keep them simple but attractive.
