The New Jersey-based hardcore band Endeavor comprised vocalist Mike Olender, guitarists Kevin Tunney and Mike Duffy, bassist Mark Zeveney and drummer Mike Rummel. After issuing their debut Crazier Than a Shithouse Rat on the Conversion label in 1997, they signed to Trustkill for the follow-up Constructive Semantics, released later that same year. ~ Jason Ankeny, Rovi
