You could start by registering the website URL in googles index by here

In google, aside from keywords, a sites rating on Google also depends on links to the site from other sites of similar content etc. So for instance if other artists had links from their site to your friends site that would potentially boost the rating in Google and bring that site closer to the first page of results, and this also works vice versa using links from your site to other websites.
Make sure all your pages on the site have keywords assigned which reflect the page content and make sure the HTML page source is well structured, indented and generally good tidy HTML.
