Alias for Erick Sermon. Wikipedia: Def Squad Presents Erick Onasis is considered the second album by the supergroup Def Squad, but it is actually an Erick Sermon solo album. Sermon takes on the alias of Erick Onasis and appears on every single track while Redman and Keith Murray make a few guest appearances. It was not a good release in terms of commercial and critical success. It reached #53 on The Billboard 200 despite having three charting singles.
