Agression is an American rock band from Silver Strand Beach, Oxnard, California. Agression was one of the founding bands of the Nardcore (Oxnard, California hardcore) scene and an early proponent of the skate punk genre. The band fused skate culture with the punk scene, featuring a song about skateboarding ("Intense Energy") and a Glen E.
