This would be Ab’s first music video before concentrating on his solo career. He released his second mixtape I See Dead People on January 8, 2009,and his third mixtape Allegheny AB on May 26, 2010.

Ab began making waves following the release of his fourth mixtape Who Harder Than Me, released on February 13, 2011. In 2012, AR-Ab began working on his fifth mixtape Who Harder Than Me II, which was released on October 5, 2012. The record included features from fellow-Philadelphia rapper Freeway, and rapper/producer Swizz Beatz who was already a long-time producer and associate of Cassidy during the latter’s stint with Ruff Ryders Entertainment. The collaboration, during which Swizz Beatz referred to Ab as “most important new artist in rap”, prompted speculation whether he would be signed to his label.

The following year saw the release of his sixth mixtape MUD Musik on February 28, 2013. This would be his last release before his latest round of legal trouble, which saw Ab turning himself into authorities and promptly incarcerated, in March of that same year
