A Son Unique is the third and final studio album by Ol' Dirty Bastard. It was supposed to be released after ODB's death in 2004 but was eventually shelved.[3] It was meant to be distributed by label owner Damon Dash. However, label issues prevented the album's release. Despite this, it has been available as a digital download and promo CDs had been circulating on the resale market.
On the day of its planned release, A Son Unique was made available on iTunes. The release was eventually cancelled by ODB's label, Roc-A-Fella. The album was finally going to be released in November 2009 to commemorate the fifth anniversary of ODB's death, but eventually got delayed again. As of 2024, A Son Unique has never been physically released, but available on digital music distribution services.
Before releasing A Son Unique, ODB changed his stage name from Ol' Dirty Bastard to Dirt McGirt. The working title for the album was Dirt McGirt.
