Deuce (born Aron Erlichman, March 2, 1983) is an American rapper, music producer, guitarist, and songwriter best known as a founding member of the rap-rock band Hollywood Undead. As an early creative force in the group, Deuce helped shape their sound and image before departing in 2010 to pursue a solo career. Known for blending rap, rock, electronic, and alternative influences, he developed a darker, more aggressive style marked by high-energy hooks, heavy production, and introspective, confrontational themes.

Following his departure, Deuce launched his solo career under Five Seven Music (a branch of Eleven Seven Music) and released his debut album Nine Lives in 2012, which debuted on the Billboard charts and sold over 11,000 copies in its first week. He later released Invincible (2017) and a series of EPs and remix projects, further establishing his independent artistic direction. Deuce also founded the Nine Lives (9LIVES / IX LIVES) movement alongside rapper Truth (Vardan Aslanyan), which became a core part of his branding and fan community.

Among his official releases are The Aron EP, which highlights his early solo work and production style, The Call Me Big Deuce EP (commonly referred to as the Big Deuce EP), and Nine Lives Forever, a project that revisits and expands on the themes and sound that defined his debut era. These releases reinforce Deuce’s long-standing identity as a self-producing artist with a consistent creative vision.

In recent years, Deuce has remained active as an independent artist, releasing new material such as “Turn Off The Lights,” while continuing to evolve his sound. With a loyal fanbase and a legacy rooted in both underground credibility and mainstream success, Deuce continues to create and release music into the mid-2020s.
