what type of visa do I have to get if i'm going to sign a contract with a recording label?

It would most likely be an O-1 Visa. *O (Extraordinary Alien) Visa* An O Visa is for persons who have extraordinary ability in the arts, sports, sciences or business. Because the H-1B's are used up so quickly, this is a good visa for those persons who have been in the business for quite some time or for people who have demonstrated success over the years. There needs to be an employer who will petition them. If approved, it can last up to 3 years and eventually, an application for permanent residency could be submitted. However, it might also be a P visa depending on the facts and situation.

If you're coming in to perform and have a basic itinerary of performances/events you can apply to come in on a P visa. You will need an immigration attorney to assist you with this process. Would recommend you contact an immigration attorney such as myself or another of your choice to set up a consultation to discuss this process and the type of documentation that will be required to qualify for a P visa.
