Primer 55

Primer 55 is an American nu metal band formed in Memphis, Tennessee in 1997. The name originated from the combination of Primer, meaning "something that's unfinished", [sic] and 55, which refers to Interstate 55, "the road that drugs run on to get to Chicago through Memphis". To date, Primer 55 has released two studio albums: Introduction to Mayhem (2000) and (The) New Release (2001). After disbanding for the first time in 2003 and reuniting from 2007 to 2015, the band announced another reunion in June 2025.
