Eden Daniel Pearlstein (born February 19, 1980), better known by his stage name Eprhyme (pronounced "E-Prime"), is an American Jewish rapper and producer based in Brooklyn, New York.
In his early twenties, he visited North Dakota to participate in a Native American Sun Dance, during which he had a spiritual epiphany that inspired him to re-examine his Jewish roots.
Pearlstein co-founded the hip hop group Saints of Everyday Failures alongside D-Scribe, Tha Goonie, MC Contradiction, and My Left Foot.
They performed at the 2006 Lakefair festival alongside One Block Radius and released two albums together, True Meaning of Survival (2005) and The State of the Art is Failure (2006), the latter of which featured contributions by Awol One, 2Mex, Onry Ozzborn, and members of Typical Cats.
A debut full-length, Deeper and Higher, was released independently in 2015, with Jamie Saft producing and contributions from drummer Ben Perowsky and vocalists Basya Schechter and Elana Brody, the former of whom became a full-time member of the group.
In late 2020 Pearlstein formed another group, Ruthless Cosmopolitans, with Madof, guitarist Yoshie Fruchter, and drummer Emmanuel "Manny" Laine (Wyclef Jean, Kanye West).
The idea for the group originated in August 2017 when Pearlstein wrote the song "Make America Hate Again" in the wake of the infamous Unite the Right rally and brought it to Madof.
