How to fix the backlog:

Biography articles to be assessed have some aspects of the {{WikiProject Biography}} template on their talk page, but the template may be incomplete. First, look over the article in anticipation of filling out the parameters of the {{WikiProject Biography}} template. Next, replace the {{WikiProject Biography}} template on the article talk page with the following:

{{WikiProject Biography
|living = yes,
|class = Start,
|needs-infobox = yes, 
|a&e-work-group = yes <!-- Arts and Entertainment -->
|musician-work-group = yes <!-- WikiProject Musicians -->
|needs-photo = yes, 
|listas = Perez, Alberto<!-- enter lastname, firstname for proper alphabetization -->
}}

The above {{WikiProject Biography}} template has all the answers that you will need for most situations. From your review of the article, delete those answers and parameters that do not fit the article. Then, fill in the listas parameter (e.g., last name, first name), then save. And, you are done!
