Putting together an album isn't easy. There are a lot of moving parts, from thinking of a title or concept, lining up producers, deciding on features if any and then getting them to contribute, selecting which songs need to stay or go and more. All of these things have to be well-executed. For many hip-hop albums, there is also the role of executive producer, in short, the person who makes sure the album sounds right and is put together properly. It isn't solely a one person, my-way-or-the-highway role; the artist and their team still has input, while the executive producer makes sure all bases are covered. Rappers have even become executive producers of other artists' albums. Here, XXL highlights some memorable hip-hop albums that were executive produced by rappers.
