After graduating from Bishop Ford High School in 1985, Nash majored in English at Columbia University, where he hosted a hip hop radio show. This led to the creation of the hip hop group 3 the Hard Way, which later changed its name to 3rd Bass, where he adopted the stage name Prime Minister Pete Nice. The group released two gold-selling albums before disbanding in 1992. Nice teamed up with group DJ Richie Rich, and the pair released their only collaboration, Dust to Dust, in 1993.

Pete Nice and author-radio jock Bobbito started their own label, Hoppoh Records, under the aegis of Columbia Records. The first release was Kurious Jorge's 1994 album A Constipated Monkey; Nice co-produced the album and the single "I'm Kurious." Nashville artist Count Bass D's debut Pre-Life Crisis followed in 1995, distributed by Columbia sister label Chaos Recordings, but those would be the only records released before the label folded because of creative differences with Columbia.

Nice quit the music business and devoted his time to baseball history. He owned a memorabilia shop in Cooperstown. In 2003, he published his first book, Baseball Legends of Brooklyn's Green-Wood Cemetery, under his real name. He has also been working to secure some property for an official grave site of Negro League players. His brother Brian was the Head Men's Basketball Coach at St. Francis College in Brooklyn Heights, New York.

In early 2008, Pete opened McGreevy's 3rd Base Bar, a sports bar in Boston with Dropkick Murphys' band member Ken Casey. The bar recently was named Best Sports Bar In Boston by Citysearch.

Commencing in 2007 and concluding in 2009, Nash was involved in litigation with an auction house relating to the authenticity of baseball memorabilia he consigned for sale. When deposed under oath, Nash invoked the Fifth Amendment dozens of times in response to questions about the origins of specific pieces of memorabilia. The court found in favor of the auction house, and Nash signed a court order in which he admitted to having committed fraud.
